Brief description This project aims to develop a novel metal materials design strategy to break the strength ceilings of nanocrystalline metals and bulk metallic glasses. This strategy is based on a novel concept of synergy between a bulk amorphous matrix and phase-transforming nanocrystallites embedded within. The nanocrystallites, via their uniform transformation lattice distortion, prevent the formation of shear bands in the amorphous matrix and enable collective atomic load transfer to allow the amorphous matrix to continue to load to achieve its intrinsic near-ideal strength. The amorphous matrix eliminates the grain boundary plasticity of the nanoscrystallites. This concept is novel and untested in the history of physical metallurgy.
