Abstract: High-entropy alloys (HEAs) have attracted a great deal of interest over the last 16 years. One reason for this level of interest is related to these alloys breaking the alloying principles that have been applied for many centuries. Despite this significant interest, most HEAs have been developed via ingot metallurgy. Powder metallurgy has appeared as an interesting alternative for further developing this family of alloys to possibly widen the field of nanostructures in HEAs and improve some capabilities of these alloys. In this presentation PM methods applied to HEAs are reviewed, and some possible ways to develop the use of powders as raw materials are introduced. The objective is to provide an update on some of the new opportunities that PM offers.

Time 15:00 – 15:30

Author Bio: Dr. Alper Evirgen holds a PhD degree in Materials Science and Engineering and has 14 years of experience in materials research and development projects pursued in various research groups and industrial companies. His expertise covers material property – microstructure relationships on a wide range of alloys and new alloy development for various industries and applications.

Currently, Dr. Evirgen works as a Senior Materials Scientist for Additive Manufacturing in Oerlikon AM Europe GmbH since 2017. He manages new alloy development projects and also responsible for the management of the R&D laboratories in the company.

Abstract: High entropy alloys (HEAs) are interesting candidates for powder-based additive manufacturing (AM) since they exhibit an unusual combination of properties such as high mechanical performance, good corrosion and oxidation resistance. Among many, Al-Cr-Fe-Ni HEAs were shown to demonstrate improved mechanical properties as compared to simple duplex steels, owing to their nano-scale duplex microstructures obtained through conventional processing. Laser powder bed fusion (LPBF) processing of these novel HEAs, promises even further property improvements via microstructural refinement, making them promising materials for applications where high strength and good corrosion resistance are required such as impellers.

In this presentation, processing challenges and alloy development for AM, the alloy microstructure in as-built and heat-treated conditions, alloy mechanical properties by tensile testing after heat-treatment and comparison with duplex steels will be discussed.
At last, an outlook on the potential applications of the novel HEA and a demonstrator part built via LPBF will be presented.

She has participated in more than 36 R&D projects, many of which were related with the manufacturing and characterization of light alloys & composite materials.

Abstract: ACHIEF project addresses to develop high Entropy Alloys (HEAs) for high temperature applications to be used in two Energy Intensive Industries (EIIs), Aluminium and Steel producers. HEAs will be used as 3d parts and coatings obtained by several laser-based processes (Directed Energy Deposition, Powder Bed Fusion and Laser Cladding). The materials will be designed supported by artificial Intelligence and micro modelling simulation tools. A novel methodology that merges physics- and data-driven modelling methodologies will be implemented for the evaluation of materials related Process-Structure-Property-Performance (PSPP) causalities by substituting physics-based models with fast-to-compute surrogates through the introduction of data-driven methods based on Machine Learning models.

HEAs will be fully developed at lab-scale by optimizing process parameters, in order to screen the optimum materials and coatings compositions, and then, solutions will be tested at pilot scale, including materials and process constrain evaluation by incorporating advanced high-temperature and strain Fibre Bragg Grating sensors.

Abstract: A broad overview on existing and new knowledge regarding health and environmental hazards in metal additive manufacturing (AM) are presented as an outcome of a large Swedish academic and industrial consortium project.

New knowledge includes particle emission measurements in workshops during various operations, which in most cases compared favorably with current occupational exposure limits (OELs). Additionally, we simulated the inhalation and ingestions of metal powder particles in body environments and checked in-vitro toxicity. Overall, no alarming effects have been observed so far; although exposure in workshops to metal powder and dust clearly elevates the metal content in urine and blood. Finally, all aspects of AM workshop reality are discussed in context of existing international regulations and OELs.

Abstract: The energy revolution is underway as the world strives to address climate change to achieve a carbon neutral energy future and foster sustainable growth in that future. This is impacting all aspects of energy: production, transportation, storage and utilization. Within these segments, new opportunities exist for light metals, specifically aluminum. Powder Metal (PM) aluminum is of particular interest in the transportation industry. Electric mobility demands innovative and robust solutions for thermal management, energy conversion, light-weighting and electrical conductivity for the battery systems. Research in PM aluminum has resulted in new alloys and processes that are intended to address these needs. This presentation will look at current trends and the opportunities that exist for PM aluminum.

Abstract: The energy transition to a net zero CO2 society is widely recognized as a monumental challenge. Austria is in the preferred condition to have already a renewable energy production of 70% but only related to electricity. If the complete primary energy demand is considered, only out 30% are from renewable resources (incl. biogenic and geothermal).

For all developed countries around the world, mobility and industry are the mainchallenges for decarbonization. AVL has created a study for energy end-use in a fully decarbonized energy scenario towards 2050. In this scenario, the electricity consumption will more than double compared to 2019 levels. This electricity demand can not be met by locally harvested renewables and as today Austria will stay an energy importer. In an optimistic scenario for energy import hydrogen could be available for as low as 2€/kg (equivalent to 6 cent(€)/kWh). In such a scenario hydrogen production will be a key technology for decarbonization.
AVL is since 2002 heavily involved in hydrogen technologies development from PEM stacks and systems for automotive, marine, rail and aviation applications to SOFC power-generation solutions to hydrogen production technologies based on PEM and Solid Oxide electrolysis. Various of these developments will be shown, together with industry trends and the role of hydrogen in the future mobility & energy system.

Abstract: The metal powder volumes for press and sinter applications are strongly influenced by the automotive market today. It is estimated that more than 2/3 of the volumes are used in automotive applications with the vast majority heavily tied to traditional combustion engine powertrains. Zero-emission vehicles; constructed on a combination of high efficiency motors and electronic systems, their dependency on mechanical components is far reduced compared to legacy combustion systems.

While most nations have committed to reducing or eliminating their CO2 footprint, electric & zero-emission vehicles have become a key element to the transition journey. Including additional major trends in the automotive industry (i.e.: sustainable materials, low CO2 manufacturing, as well as circularity) it is estimated how the metal powder market for press and sinter could evolve. For the PM landscape this is not only an industry evolution but one which can bring new opportunities even beyond automotive.

Abstract: Clean energy technologies require a variety of minerals and metals, and today’s tense geopolitical situation, rising commodity prices and supply chain bottlenecks have highlighted the need for serious actions to enhance the diversity and resilience of their supply.

Prices of many minerals and metals that are essential for clean energy technologies have recently soared due to a combination of rising demand, disrupted supply chains and concerns around tightening supply. The prices of lithium and cobalt more than doubled in 2021, and those for copper, nickel and aluminium all rose by around 25% to 40%.

The content of this 12 years activity was research, product & process development and market analysis in close collaboration with manufacturing.

Abstract: Copper and Nickel are the main alloying elements in low alloyed, sintered steels. The fast expansion of the new energy technologies in cars and in energy generation put a strong challenge on pricing and availability of these metals. The presentation shows solutions by introducing other alloying elements and modifications in the sintering process. This will lead to cost reductions for the material and the sintering process: a ‘win win’ situation!

Her main research focus is on sintering phenomena, particularly in liquid phase sintering mechanisms and the influence of oxidation/reduction mechanisms. She has worked intensively in the design of liquid phase formers for sintered steels supported on the use of thermodynamic software tools. In the last years she has also focused on the “tailored” design of novel binder compositions for hardmetals. She is author of more than 40 articles in peer-reviewed journals (16 invited) and 2 book chapters in encyclopedias, and she has participated as invited/keynote speaker in 10 International Scientific Conferences. She is member of the editorial board of the journals “Powder Metallurgy” and “Powder Metallurgy Progress”.

Abstract: The Masteralloy (MA) alloying route has a great potential for reducing the alloying costs in sintered materials, while allowing the introduction of innovative alloying systems. However, in order to achieve an efficient use of the alloying elements, the particle sizes needed are often below 25 µm, which means that for standard gas atomization a significant fraction of the batch has to be discarded or at least recycled. This presentation shows how, in the last years, the combination of novel tools for liquid phase design, and new atomization techniques have overcome the main limitations for the use of masteralloys in the production of sintered steels. In this new frame, the use “masteralloys” can become a real alternative for PM steels, giving the possibility of enhancing sintering by using liquids with tailored compositions and thus tailored behaviours.

Abstract: The additive manufacturing (AM) market is rapidly expanding in several industrial applications as an alternative low-cost and quick manufacture technique, attracting yearly more and more a great diversity of users. Sustainable and safe-by-design approach demands increased production efficiency to be combined with a deep awareness of the environmental and human health risks related to AM processes. Therefore, an emerging need for a ready-to-use approach to eliminate the risks and mitigate the occupational exposure as well as the environmental concerns to this widely used technology has been revealed. Thus, it is crucial to ensure occupational and product safety, following an adequately environmental management of materials and energy to foster the sustainable deployment of this growing technology. Sustainable performance of new technologies is an ultimate goal that will offer substantial possibilities for improving the competitive position of the EU and for responding to key societal challenges.

Abstract: Due to the combination of high hardness, high compressive strength, good corrosion resistance, and excellent resistance to wear and abrasion, cemented tungsten carbide based hardmetals have been used for almost a century for numerous wear and cutting tool applications. Hardmetals in the past have primarily been processed by press and sinter and more recently by powder injection molding both of which require the use of expensive tooling. Additive manufacturing (AM) on the other hand is a process that has the capability of fabricating complex shapes without the need for any tooling. This presentation will discuss two sinter-based AM processes for fabricating hardmetal parts. One of the processes is based on material extrusion while the other is based on the technology of binderjet (BJ).

Abstract: Political and economic situation is changing in the world more rapidly today than for many years in the past. In addition to that, global climate warming puts pressure on companies and societies to make their efforts to reduce risk for large climate crisis. Cemented carbides are used in many applications like metal, wood and stone cutting, mining and construction industry, general wear parts and many others. Tungsten carbide as well as the most used binder element, cobalt, are produced by powder metallurgical processes either from virgin raw materials or from secondary raw materials. Both tungsten and cobalt are scarce in the earth crust and the production requires high amount of energy and chemicals. The supply chain of both elements is volatile in terms of price and availability. European Commission has listed tungsten and cobalt as critical raw materials due to economic importance and supply risk. Recycling can reduce the supply risks, stabilize the prices and reduce the environmental impact of hard metal production. In the design of new hard metal tools, recycling aspects should be considered already in early development phase as tool design can have big influence in the recyclability of carbide tools. In this presentation, trends and current issues in the tungsten carbide recycling are reviewed and possible developments in the future are discussed.

Abstract: The presentation will report on the recent development of tooling solutions based on ultrahard (cubic boron nitride, diamond) and ceramic cutting tool materials for machining difficult to cut materials (e.g. Nickel based alloys, Titanium).

Author Bio: Jeffrey Taylor is the President of Crafts Technology, which is part of the Precision Solutions group of the Hyperion Materials & Technology (HMT) company. While HMT is a leader in advanced materials with decades of experience developing and manufacturing tungsten carbide powder, cemented carbide, industrial diamond, and cubic boron nitride, Crafts Technology and the Precision Solutions group specializes in the conversion of the powdered metallurgy products into finished high precision and high-performance engineered tooling and wear solutions.

Abstract: Tungsten carbide powdered metallurgy has played a critical role in the development of high precision injection mold tooling over the past decade, having essentially become the Best Available Technology (BAT) as it relates to the design and utility of tooling components such as core pins, valve gate bushings, nozzles, and inserts.

Some of the highest precision and highest volume plastic automotive components, medical consumables, and consumer goods in the world are now being produced at speeds and quality levels previously unattainable with commonly used hardened steels, aluminum and beryllium copper alloys.
Tungsten carbide powder metallurgy has afforded tool designers and fabricators the ability to design tooling that can significantly improve tool rigidity and wear life while also improving thermal conductivity and reducing the coefficient of friction. These are attractive features in a tool design as mold builders and molders alike regularly endeavor to improve part quality and reduce cycle time, while also being able to more easily eject parts from the mold and reduce mold maintenance intervals. Molders and mold builders no longer have to sacrifice or trade off these benefits when they elect to utilize tungsten carbide in their tooling designs.

Abstract: A significant part of the cemented carbide materials produced worldwide is used for rock drilling tools in mining operations. In this application area, the materials need to combine high wear resistance with relatively high toughness levels – typically higher than those common in cemented carbides used in cutting tools. The increased performance requirements for today’s rock drilling tools require the material properties to be tailored to various specific application areas within the mining industry, including various drill bit designs, different rock types and other factors. Traditionally, the challenge in designing these materials to reach the target performance has been viewed as improving wear resistance on one side while not losing (or even increasing) toughness on the other side. The present talk will aim to move beyond this perspective, focusing on the more complex set of properties relevant to premature tool breakages in mining applications, and briefly outlining how these are related to the basic parameters of cemented carbide microstructures.

Abstract: The elaboration of Nuclear Power Plant primary circuit pipework currently relies on forging|casting and machining processes. However, to maintain performance and competitiveness, Framatome and EDF decided to take advantage of Powder Metallurgy Hot Isostatic Pressing (PM+HIP) benefits and launched a pre-industrialization project. It is intended to demonstrate the ability of the supply-chain to produce an 8 tons 304L primary elbow in compliance with the nuclear requirements and to address the corresponding documentation. The manufacturing of the elbow was entrusted to Bodycote, which has recognized expertise in this area. The presentation will go over the fabrication of this large component and will then provide characterization results confirming the compliance with EDF|Framatome’s requirements.

Abstract: The most significant change in the production methods for tool steels and high-speed steels has been the rapid advance of powder metallurgy (PM) for production of the most highly alloyed steel grades. The ability to overcome production problems of conventional static ingot metallurgy route stem from the fundamental ability of the process to produce a fine and uniform distribution of carbides as a result of rapid solidification during atomization. However, the highly spherical nature of the used powders means that final parts cannot be produced by the conventional press- and sinter-technique due to the lack of adequate green strength. Thus, hot isostatic pressing (HIP) has become the most common consolidation technique for PM tool steels and high-speed steels. In this presentation, the state of the art PM production of different tool steels and high-speed steels will be discussed in terms of advantages and disadvantages. Furthermore, special focus is laid on the influence of HIP temperature, pressure and holding time on the microstructure.

Abstract: Net shape powder metallurgy and Laser-Powder Bed Fusion Additive manufacturing have been established as disruptive novel manufacturing routes in many industrial sectors. Baker Hughes has been applying these technologies in products for the energy market, as turbomachinery. Nevertheless, the modeling of these processes still faces technical challenges. The modeling of a process as Hot Isostatic pressing for Net shape powder metallurgy shall include all source of variability all along the process, and are not limited to the densification itself, like digital tool errors, powder distribution during filling, heat transfer during cycles).On the other hand the modeling of L-PBF shall provide printability maps that take into account the thermal history of the build, as well as the expected deformation of the parts during printing. The speech intends to present the critical aspects of these topics and the BH expertise on the subject.

Abstract: One of the many benefits of Powder Metallurgy and HIP is the ability to manufacture unique materials and material combinations. The presentation aims to provide a detailed overview on two classes PM HIP hybrid materials: PM HIP Metal Matrix Composites and compound materials. Several examples of PMHMMC materials targeting high wear resistance are presented and fundamental manufacturing aspects are covered. Results show that is possible to manufacture highly wear resistant PMHMMCs, but care must be taken to use the right materials and process parameters. The use of compound materials targets the placement of the properties desired in the exact area of a component without any compromise, consequently boosting the performance of the components. Several examples of compound materials are presented and an overview of important aspects of manufacturing are covered. The results clearly show that due attention must be taken when choosing materials and processing parameters in order to achieve optimal results. Finally, actual product examples are presented to highlight where limitations, challenges, and in the end the solutions were created displaying the clear benefits of PM HIP. The conclusions presented will lead to further interest and investigation into the highly effective use of PM HIP Hybrid materials.
