TL;DR: In this article, the lattice parameters of quaternary shape memory alloys and the thermal hysteresis were tailored by using a thin-film composition-spread technique and high-throughput characterization methods.

TL;DR: In this paper, the concentration dependence of the martensite start temperature (M S ) in Ni-Ti-based shape memory alloys (SMAs) was investigated and it was shown that the strong dependence of M S on alloy composition in binary, ternary and quaternary SMAs is due to a stabilization of the B2 phase by structural relaxations around Ni antisite atoms.

TL;DR: In this article, the authors examined the influence of the ternary elements on the corrosion behavior using standard electrochemical techniques and proposed a relation between the NiTi-based alloys and their localised corrosion resistances.

TL;DR: In this paper, it was shown that a good crystallographic fit is associated with a small mechanical hysteresis width, observed during a forward and reverse stress-induced transformation.

TL;DR: In this paper, a chemical and micro-structural optimization of Ni-Ti for ferroic cooling is presented, where a large number of Ni−Ti-based alloy compositions were evaluated in terms of phase transformation temperatures, latent heats, mechanical hysteresis widths and functional stability.
