Influence of Composition on Shape Memory Characteristics of Ti-Ni-Cu Alloy Fabricated by Pulse-Current Pressure Sintering Method

Abstract

This paper aims to find out the influence of composition on shape memory characteristic of Ti-Ni-Cu alloy fabricated by pulse-current pressure sintering method. In the case of Ti powder, the solution-treatment results in decreasing in relative density. On the other hand, in the case of TiH_2 powder, the solution-treatment results in increasing in relative density, but decreasing in tensile strength and elongation. The increase in Ni equivalent value made the transformation temperatures lower.
