Effect of thermal cycling on structure and properties of Ni–Mn–In-based alloys

The results of investigations of the structure and properties of ternary alloys Ni_47–xMn_{42 + x}In₁₁ (0 ≤ x ≤ 2) after thermal cycling are presented. It has been shown that multiple cycles of heating and deep cooling result in a change in the shape of grain boundaries and an increase in microhardness. Thermal cycling does not cause any significant changes in the magnetic susceptibility of the investigated alloys.
