Abstract:
This talk will focus on in-situ mechanics for studying the mechanical behavior at atomic scale for nanometer-sized twins, single element metallic glass, and crystal BCC metals. In comparison to computational molecular dynamics, the experimental molecular dynamics with the in-situ high-resolution TEM is going to open a new approach to directly observe atomic-scaled deformation with in-situ mechanics. I will cover the high stress induced lattice disturbance, dislocation dipole nucleation and competition between slip and twinning in the deformation process of nano-sized body center cubic metals and deformation in single elemental metallic glasses.
