Abstract:
The behavior of the shape memory alloy NiTi is governed by a phase transformation between a high temperature cubic austenite phase and a low temperature monoclinic martensite phase. The transformation can be triggered either by 1) temperature cycling between the phases (shape memory effect), or 2) load cycling between the high strain martensite phase and the low strain austenite phase (pseudoelasticity). The phase transformation behavior of the material depends on temperature, volume fraction of the two phases and imposed loading.
