Research Interests

Mechanical properties of ceramics and metals. Of particular interest is to understand how low temperature deformation twinning is related to plastic deformation by dislocation slip at elevated temperatures. Deformation twinning models for both basal and rhombohedral twinning in sap-phire, which are properly related to dislocation slip at elevated temperatures, have been estab-lished. The basal twinning model has been confirmed experimentally using TEM techniques. Cur-rent research involves studies on how to generalize this twinning model to other materials systems; i.e., metals, intermetallic compounds and other ceramics.
