Abstract

Microstructure, phase transformation and stress-strain behaviors of a Ce-added laser welded TiNi alloy have been studied. An Nd:YAG laser was used for butt fusion of two Ti-50.9Ni alloy plates with a (Ti-50.9Ni)-5Ce stripe pre-assembled between their joint. Microstructure, phase constitution, phase transformation and stress-strain behavior of several TiNi alloy specimens were researched with SEM, XRD, DSC and tensile test, respectively. Unlike the typical monotonous superelasticity of base metal and Ce-free welded TiNi, the Ce-added welded TiNi specimen shows a peculiar two-stage superelasticity. Based on results of SEM, XRD and DSC tests, a mechanism for the two-stage superelasticity has been discussed.
