Abstract

Multi-principle element (MPE) alloys (also called high entropy alloys) have 5 or more elements at roughly equivalent concentrations. The vast number of new alloy systems created by this approach gives dramatic new opportunities for discovery and development. However, the immense number of alloy systems also represents the most significant technical barrier. A palette of 40 metal elements offers over 10^10 MPE alloy systems, so that fundamentally new methods are needed to design and evaluate alloy systems rapidly, systematically and effectively. A 3-stage approach is described to rapidly screen and evaluate vast numbers of MPEs for aerospace applications. CALPHAD methods that calculate phase equilibria are integrated with high-throughput experiments on materials libraries with controlled composition and microstructure gradients. Much of this evaluation can be done now, but key components are missing. This ICME methodology will be described, current results will be presented, and required future efforts will be outlined.

Dr. Daniel Miracle

Dr. Daniel Miracle is the Chief Scientist in the Materials and Manufacturing Directorate of the Air Force Research Laboratory (AFRL). Within the Materials and Manufacturing Directorate, he is responsible for the quality, balance and focus of the technical program; the quality and balance of the technical workforce; oversight of innovation programs; and infrastructure needs. He is a member of the AFRL Research Council and is the senior technical interface with universities, industry and the international scientific community on all issues relating to aerospace materials and processes. Dr. Miracle advises on and evaluates the need for scientific and engineering research and development programs having national and/or international significance. He has conducted research in the areas of nickel-based superalloys and intermetallic compounds for high temperature structures; metal matrix composites for structural and thermal applications; advanced aluminum alloys for cryogenic components; and boron-modified titanium for improved processibility. Current research interests include basic studies of amorphous metals and multi-principal element alloys. Dr. Miracle received a B.S. degree in Materials Science and Engineering from Wright State University, M.S. and Ph.D. degrees in Metallurgical Engineering from The Ohio State University, and an Honorary Doctor of Science from the Institute of Metal Physics, Ukrainian Academy of Sciences, Ukraine. Additional positions held include Senior Visiting Fellow at Cambridge University (Cambridge, UK), Tohoku University (Sendai, Japan) and University of Sydney (Sydney, Australia); Adjunct Professor of Wright State University; Scientific Officer at the AF Office of Scientific Research; Senior Scientist, Materials for Micro and Nano Systems at AFRL; and Chair of the AFRL Strategic Technology Team for Nanoscience and Technology. Dr. Miracle is a Fellow of ASM, International and a Fellow of the Air Force Research Laboratory. Dr. Miracle has received the AF Basic Research Award, the AF Scientific Achievement Award, and was co-recipient of the DoE Outstanding Scientific Accomplishment award. He is author or co-author of over 190 peer-reviewed scientific articles and 6 book chapters, and is co-editor of 6 books, including Composites, Volume 21 of the ASM Handbook series. Dr. Miracle is co-inventor on 8 patents and has given over 130 invited and keynote talks at national and international scientific venues.
