Structural transitions in a NiTi alloy: a multistage loading-unload cycle

Show other versions (2)

NiTi shape memory alloys (SMAs) are increasingly used in many engineering and medical applications, because they combine special functional properties, such as shape memory effect and pseudo-elasticity, with good mechanical strength and biocompatibility. However, the microstructural changes associat...
