A Bulk metallic glasses (BMGs) are alloys that can be cooled from the liquid without crystallization, resulting in a glassy, amorphous solid. Sufficiently stable BMGs can be processed like plastics if the temperature is held in the supercooled liquid region, resulting in net-shape, seamless forming of complicated shapes by blow molding and rapid fabrication of nanostructures across large areas by hard-mask imprinting. This project will develop a new methodology for discovering new BMG alloys using an iterative strategy of state-of-the-art experimental and computational tools that advances the objectives of the Materials Genome Initiative (MGI). The method requires the integration of experiments and simulations with tight feedback between the four investigators with complimentary expertise to provide new scientific insights. The novel integrated computational and experimental approach, combining structure up to the nanometer scale and the kinetics of both glass formation and crystallization, may be transformative in yielding a unique combination of tools and approaches that may lead to a general method to design new BMGs alloys for a variety of applications.
