Thermomechanical fatigue of post-weld heat treated NiTi shape memory alloy wires

Welding and Joining of NiTi Shape Memory Alloys: A Review

“…Early laser welding studies on NiTi shape memory alloys were performed using CO ?2 lasers [31,[125][126][127] while, nowadays, the primary choice for these studies are the infrared lasers, such as Nd:YAG [128][129][130][131]145,165,166] and fibre lasers [132][133][134] due to their low wavelength and increased material absorptivity and, thus, narrow welds [38,135].…”

A study on the corrosion fatigue behaviour of laser-welded shape memory NiTi wires in a simulated body fluid

“…Chan et al [11] reported the fatigue fracture mechanisms of NiTi laser joints when subject to small strain in BRF. Panton et al [12,13] investigated the thermomechanical fatigue properties of laser-welded and post-weld heat-treated NiTi wires using a custom design setup. On the other hand,…”

Innovations and recent trends in Shape Memory Alloy: a review

“…Experiment was done for observing the thermomechanical fatigue of post-weld NiTi SMA. YAG pulsed laser welding process was used for fabrication process [6]. It was observed that 86% of the tensile strength was maintained, but the actuation stability and cycle life was decreased.…”

“…Ni-Ti alloys are expensive, hence researcher are trying to make different types of SMA's that are economical and have more physical properties as compared Ni-Ti. [6]. Gold based was the first identified shape memory material.…”
