AbstractThe in situ investigation of the effects of stress induced martensitic transformation (SIMT) on fatigue behavior in TiNi shape memory alloy (SMA) was conducted using a quester remote measurement system (QRMS). The effects of SIMT on stress-strain response, crack initiation and propagation of fatigue were investigated. Being compared with normal alloys, the result shows that the reversible SIMT improved the fatigue properties, but it also is the cause resulting in the slip which leads to the crack initiation. Some abnormal behaviors in SMA were discussed, such as the dependence of propagation rate to crack length in constant DeltaK control fatigue tests, the phenomenon of crack branches and secondary cracks etc.
