Education
- Ph.D. Ohio State University 1989
- M.S. Ohio State University 1986
- B.S. Timisoara Polytechnical Institute 1976
Current Research Interests
- Solid-state weldability of High Performance Steels for bridges (Friction Stir Welding and High Frequency welding hybrid process development). Microstructure/property relationships, numerical modeling, Gleeble simulations.
- Microwave Welding of thermoelectric generators using Ni and Al powder at the interface between Bismuth Telluride and copper. Thermal cycling, intermetallic layer growth, improve Figure of Merit.
Previous Research Interests
- Hydrogen-induced cracking susceptibility of High Performance steels
- Effect of oxygen contamination on Ni-based superalloy ENi3Fe GTAW deposit wettability on 304 stainless steel and Ductility Dip Cracking susceptibility
- High Frequency Induction welding simulations on SAE 4130, A 304 austenitic and type 2507 duplex stainless steels and Al 6061 aluminum alloys
- Stud welding on Zn-coated beams (HDG and EG, as well as conductive paints)
- Resistance Brazing of W-C powder product on Cu substrate for circuit breaker contacts
Patents
