Effect of ageing treatment on the transformation behaviour of Ti–50.9 at.% Ni alloy
TL;DR: This article investigated the effect of ageing on the transformation behavior of a Ti-509% at% Ni alloy and found that aging at below 573 k was found to suppress the original A-↔-M transformation.

Laser welding of NiTi shape memory alloy: A review
TL;DR: In this paper, the effects of laser welding process on the functional properties of NiTi and related alloys are investigated, and the impact of the post-weld heat treatment (PWHT) is studied as an effective solution to improve the downsides of the Laser welding process.
Journal ArticleDOI
Orientation dependence of stress-induced phase transformation and dislocation plasticity in NiTi shape memory alloys on the micro scale
TL;DR: In this article, a binary, solution annealed precipitate free NiTi alloy was used to compress small pillars in three directions: 1, 2, 3 and 4 directions.

Ni4Ti3-precipitation during aging of NiTi shape memory alloys and its influence on martensitic phase transformations
TL;DR: In this paper, the microstructure of a Ni-rich NiTi shape memory alloy and its influence on the thermal characteristics of martensitic transformations were studied. But the authors did not consider the effect of stress on the precipitation process of Ni4Ti3-precipitates.
