The main focus areas of our research group are processing-microstructure-mechanical property relationships in advanced metallic materials, severe plastic deformation, martensitic phase transformation, deformation twinning and micro-mechanical constitutive modeling of deformation mechanisms. The materials currently under investigation are:
1. Conventional Shape Memory Alloys (Ni-Ti)
2. High Temperature Shape Memory Alloys (Ni-Ti-Hf, Ni-Ti-Pd, Ni-Ti-Pt)
3. Ferromagnetic Shape Memory Alloys (Co-Ni-Al, Co-Ni-Ga, Ni-Mn-(Ga,In, Co) and
Fe-Co-Ni-Ti)
4. Bulk Metallic Glasses and Composites (Vitreloys and their composites)
5. Bulk Nanocrystalline Materials (Ti, Nb, Mg, Al, Cu and their alloys,
Stainless Steel and NiTi)
6. Austenitic Steels (Hadfield Steel and Stainless Steels)
7. Interstitial Free (IF) Steels
We use the following tools in investigation of these materials:
· Materials Synthesis and Processing (Vacuum arc melting, Equal Channel Angular Extrusion or Equal Channel Angular Pressing, Micro and Nano Powder Consolidation, rolling, wire drawing, etc.)
· Mechanical Testing (Monotonic and cyclic testing of single crystals and polycrystals at temperatures from -100 ºC up to 1000 ºC)
·
Microstructural investigations (Optical
microscopy, SEM, TEM, X-Ray, OIM)
· Modeling (Microstructure evolution based crystal plasticity models)
The group's research is funded by several funding agencies such as NSF - CMII, NSF - DMR, NSF - EEC, ARO, ONR, NASA, and The U.S. CRDF.
Our group has an extensive national and
international collaboration with the scientists from
