Abstract

The phase equilibria at 900 °C and B2/L2₁ order-disorder transition in the Ni-Mn-Ga ternary system were investigated by analyzing the equilibrated alloys and diffusion couples using a combination of techniques. It was confirmed that a bcc single phase region exists in a wide composition range at 900 °C, and the critical temperatures of B2/L2₁ order-disorder transition were determined in Ni-50 at.% section, which exhibits a maximal ordering transition temperature of 796°C at Mn content of 25 at.%. The obtained results will be helpful for the preparation and annealing of Ni-Mn-Ga alloys in the specific temperature.
