Comparison studies on phase formation and transformation behavior between Ni-Ti and Ni-TiH2 synthesized via solid state sintering

Solid state synthesis is an alternative processing technique that has been attempted for producing novel-structured NiTi such as porous NiTi and other novel forms. Whilst shape memory effect is a unique advantage of NiTi shape memory alloy like, no successful attempt so far to produce single phase N...
