The objective of this research program is to identify relationships between characteristics of intermetallic alloys at an atomic scale, the operation of slip and twinning deformation mechanisms at a microstructural scale, and bulk deformation and fracture properties. Our research focuses on two fundamental aspects of the problem of low toughness of intermetallic alloys The role of deformation twinning in promoting ductility and toughness of ordered intermetallic alloys, and modeling the effect of dislocation characteristics on crack tip plasticity.
