Processing of bulk amorphous alloys, composites and coatings using relatively novel spark plasma sintering processes

Faculty: Sandip Harimkar, Ph.D.

Amorphous alloys exhibit outstanding mechanical and electrochemical properties due to their disordered atomic structure. However, it is difficult to fabricate bulk useful shapes of these materials using conventional casting technologies. In this project, processing of bulk amorphous alloys, composites, and coatings will be investigated using relatively novel spark plasma sintering processes.
