The National Science Foundation awarded the University of Illinois a $150,000 Project Grant under the Mathematical and Physical Sciences program (CFDA 47.049) to conduct collaborative research on nanoscale structural and compositional instability-driven ductility in refractory high-entropy alloys. The research will develop an atomic-level understanding of how the manufacturing of refractory high-entropy alloys relates to their ductility and tensile strength properties. It will also seek to increase the ductile strength of these alloys through twinning-induced plasticity and transition-induced plasticity, which can result in distortions to the crystal lattice. The University of Illinois will detect these lattice distortions using a data mining-based transmission electron microscopy approach and characterize new alloy materials. Results are expected to aid in the design of new refractory alloys and have broad impact on other alloy research. The award period is from December 1, 2022 to November 30, 2024.
