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.

Daniel Miracle, Senior Scientist, Air Force Research Laboratory, Materials and Manufacturing Directorate
Dr. Dan Miracle, a member of the scientific and technical cadre of senior executives, is the Senior Scientist, Materials for Micro and Nano Systems, Materials and Manufacturing Directorate, Air Force Research Laboratory, Air Force Materiel Command, Wright-Patterson Air Force Base, Ohio. He shares responsibility to define, advocate and implement a strategic vision for nanoscience and technology within the Materials and Manufacturing Directorate and across the directorates in the AFRL. He works with the other services in the Department of Defense to coordinate and integrate science and technology efforts in nanoscience and technology, and represents the Air Force strategic vision at the national and international level.
Dr. Miracle has conducted and led research and development on a range of metallic materials for Air Force structural applications, including nickel-based superalloys, high strength aluminum and titanium alloys, high temperature ordered intermetallic alloys and metal matrix composites. Dr. Miracle’s current research on amorphous and nanocrystalline metals is providing the scientific foundation required to lead the exploration and development of these materials for structural and functional Air Force applications. He has made seminal contributions to the field of metallic glasses by defining the atomic structure of these materials, and is presently engaged in defining the principles of chemical stability in advanced metallic materials. Dr. Miracle has written or co-written more than 150 technical articles, six technical chapters, and is co-editor of six books, including Composites, Volume 21 of the ASM, International Handbook Series. He is co-inventor on six patents.

The real value of the event will come through the dissemination of a report outlining key recommendations identified at the workshop. The report will be shared with public and private sector stakeholders in the position to take action towards advancing U.S. competitiveness in high entropy alloy manufacturing. Stay tuned for more information about the outcomes of this workshop.
The goal is for the report to be released in April 2018.
