Project title: Wear resistance of NiTi shape memory alloys
Shape memory alloys (SMAs) are unique due to the reversible phase
transition between the low-temperature martensite
phase and the high-temperature austenite phase. Nickel titanium (NiTi) SMA exhibits the well-known shape memory (SME) and superelasticity (SE) effects. Superelastic
behavior refers to a case where a reversible austenite-martensitic
phase transition can be induced by applied stress and is recoverable as the
stress is removed. Due to its outstanding superelastic
behavior, NiTi SMA has been increasingly used in
medical surgery and considered as a possible functional material for microelectromechanical systems (MEMS). In these
applications, the stress-induced phase transition process is unavoidable due
to the local high contact pressure, and therefore may play an important role
in the wearing of NiTi.
