## Abstract Starting from NiTi‐powders, composites of nickel‐titanium shape memory alloys (NiTi‐SMA) and different stainless steels as well as of different NiTi‐SMAs were produced by using the process of hot isostatic pressing (HIP). Metallographic investigations focussed on the interface between N
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
