Phase Transformations
Currently, I am trying to study and understand the glass transition with respect to metallic materials. We are attempting to model and simulate amorphous phase formation during various non-equilibrium processing techniques like high-energy ball milling and rapid solidification. Presently, we are trying to look only at binary alloys.
Another related topic of interests involves the nature of diffusion in mechanical alloying. The role of ballistic diffusion in mechanical alloying is widely accepted. However, if one can carry out the process at high temperatures, it is possible that we can observe a switch from ballistic to thermal diffusion as the key controlling mechanism.
A third related topic of interest is undercooling of binary alloys. We looked at the microstructure development during undercooling of Ni-P alloy. Presently, we are focusing on the undercooling of a number of glass forming binary liquids with the hope of elucidating the mechanism of glass formation.
