This website is built for a research project entitled “Collaborative Research: DMREF: NSF-DST: Metastability engineering in refractory multi-principal element alloys”. It was jointly funded by the U.S. National Science Foundatoin and the Department of Science and Technology, Government of India. The five U.S. PIs are:

This project aims to establish a transformative framework for the development of structural alloys that simultaneously achieve high strength at high temperatures and enhanced ductility at room temperature. The research focuses on a relatively new class of metallic materials known as refractory multi-principal element alloys (RMPEAs), which are recognized for their high-temperature strength but typically suffer from limited plasticity under ambient conditions. The team will develop the new alloy design paradigm through a concept called “metastability engineering,” which activates novel nano-scale deformation mechanisms by controlling dislocation dynamics and phase stability. The research integrates combinatorial synthesis, advanced in-situ experiments, atomistic and mesoscale simulations, and machine learning-guided discovery. The resulting framework will enable accelerated design of high-performance RMPEAs across broad temperature ranges. In parallel, the project will contribute to training a new generation of materials scientists in experimental, computational, and data-driven methods, while supporting outreach and international collaboration through partnerships with five US universities and one Indian university.
