Since the discovery of NiMnGa shape memory alloys, including the ferromagnetic shape memory alloys and high-temperature shape memory alloys, the severe brittleness, especially the grain-boundary brittleness, has been a crucial bottleneck hindering their development. Here, high plasticity is reported

This paper is dedicated to the first observations of the martensitic transformation (MT) and shape memory effect in Ni 3 Ta intermetallic compound. It was found that Ni 3 Ta undergoes MT with 50 K temperature hysteresis at elevated temperatures (M s = 530 K, M f = 500 K, A s = 550 K, A f = 580 K). T
In this study, the effect of Ta content on shape memory behavior of Ti-Ta alloys was investigated. The shape memory effect was confirmed in Ti-(30-40)Ta alloys. The martensitic transformation start temperature (M s ) decreased by 30 K per 1 at.% Ta. The amount of x phase formed during aging decrease
