Interrelation of Deformation

One of my research interests, pursued in collaboration with R. Yund, H. Stunitz and others, has been experimental studies of the kinetics of solid state processes influencing deformation, such as diffusion, disordering, grain growth, and other processes, as well as the mutual interactions of deformation and phase changes.
