Phase equilibria at 700 and 850 °C, critical temperatures of B2/L2 1 order-disorder transformation and martensitic and ferromagnetic phase regions at room temperature in the Ni-Mn-In system were determined mainly by diffusion triple method using a two-stage diffusion couple technique. It was confirmed that a single phase region of the β phase at both 700 and 850 °C exists in a wide composition range along the NiMn-NiIn section and that the L21 ordered phase region appears in the vicinity of Ni 2MnIn in the temperature region below about 800 °C. The composition lines, iso-Ms and iso-TFM, possessing the Ms and TC temperatures at room temperature, respectively, were successfully estimated and the coincidence between the iso-Ms and iso-TFM was confirmed in the composition region from 10 to 20 at.% In in the β-phase region.
