MANUFACTURING HIGH-ENTROPY ALLOYS
OUTCOMES
KEY RECOMMENDATIONS
In line with MForesight’s mission of providing coordinated input from the manufacturing community to inform national priorities in advanced manufacturing, the advanced manufacturing community found four clear and actionable recommendations for boosting U.S. competitiveness in HEA manufacturing:
1. Invest in critical translational research for HEA manufacturing, from the earliest alloy identification to processes enabling final part production. HEA processing technologies need to be developed past the prototype stage to enable scalable manufacturing.
2. Establish a National Testing Center for HEAs focused on high-throughput testing to enable rapid discovery, testing, and validation of HEAs and manufacturing processes.
3. Develop a central database for HEA data to minimize duplicative efforts and accelerate innovations by U.S. researchers and manufacturers.
4. Enhance collaborative efforts through increased access to federal facilities and expertise and through the establishment of an interdisciplinary working group. Leveraging and aligning existing federal resources and efforts are essential to HEA manufacturing progress.
DISSEMINATION
The real value of this work comes through the dissemination of the key recommendations identified by the advanced manufacturing community represented at the workshop. The report and summary have been shared with public and private sector stakeholders. Specifically, MForesight published A Call to Action: Manufacturing High-Entropy Alloys in the Journal of Materials Research, hosted federal agency briefings at the Department of Defense and Department of Energy, and highlighted the report in the following briefing on Capitol Hill.
Capitol Hill Briefing: Next Generation Materials for Manufacturing Competitiveness
October 3, 2018
10:30 am
2020 Rayburn House Office Building
Hosted in conjunction with the House Manufacturing Caucus
Manufacturing is a cornerstone of the U.S. economy and it is imperative that U.S. manufacturing remains competitive and capitalize on areas for growth and innovation. Breakthroughs in new materials technologies are a critical component of the technological advances needed to bolster next generation manufacturing in the United States. Materials technologies are involved at every step within the manufacturing process chain from novel feedstocks to shaping technologies, to advanced sensors, and ultimately, to high performing products.
Driven by insights from the U.S. advanced manufacturing community, this briefing explored some of the most promising materials innovations that could enable the next wave of manufacturing technologies as highlighted in the MForesight report, Harnessing Materials Innovations to Support Next Generation Manufacturing Technologies. The briefing highlighted two promising technologies, Metamaterials and High-Entropy Alloys, and explored pathways to support industrial competitiveness based on the collective voice of manufacturers, government agencies, and leading research institutions.

Overview/Motivation
High Entropy alloys (or HEAs) are a type of multi-principal element alloy (MPEA) that have 5 or more alloying elements in roughly equal proportion, with a minimum threshold of entropy. MPEAs are a broader class of special alloys where the number of alloying elements in roughly equal proportion is more flexibly defined, and there is no requirement on the alloy’s entropy. This broader class is also sometimes referred to as Complex Concentrated Alloys (CCAs). This workshop will address all types of MPEAs, including the subset of HEAs. Such advanced alloys have applications in light-weighting, high-temperature environments (e.g. turbines), catalysts, coatings, magnetics, rare-earth replacement, and a range of other areas that require extraordinary material properties, unique combinations of properties, or seek to reduce the use of costly materials. The near-infinite permutations of elements offers metallurgists the potential ability to design targeted alloys with specifically desired combinations of properties and ultra-high performance. Yet manufacturing these advanced alloys at scale has proven to be a substantial barrier to realizing their potential. Challenges range from alloy discovery & development to melting, casting, deposition, and application. We hosted the High Entropy Alloy Manufacturing Workshop to detail barriers to the translation of high entropy alloys from the research lab to the factory, identify solutions to these barriers, and lay out actionable next steps to realize the solutions. Findings will be disseminated through a formal report and policy briefs addressed primarily to public sector stakeholders. Event contact: [email protected]
