(This along with three other papers in Ti-alloys is the work started during my tenure in GM and still ongoing in collaboration with GM and UC Davis. This work focuses on developing fundamental understanding of the effect of electric field and other processing parameters in the sintering kinetics of Ti-alloys) Technological:
