I am a visiting scholar at Northwestern University, supervised by prof. David Dunand in Materials Science and Engineering. I am studying NiTiNb foam scaffolds for biomedical applications, which have good shape memory effect and superelasticity. It is based on the use of pure niobium as a melting-point depressant that can induce contact melting with NiTi at tractable temperatures. I am working on creating the structure of NiTiNb scaffold and studying the phase transformation and microstructure of this NiTiNb foam. Further superelastic mechanisms will be researched.
