Abstract

•The isothermal section of the Ni–Mn–In ternary system at 773 K was determined.•XRD, EPMA techniques were used.•13 single-phase, 27 two-phase and 14 three-phase regions were obtained.•7 binary compounds and 2 ternary compounds were confirmed.•The homogeneity ranges of the ternary compounds T1 and T2 were determined.

The isothermal section of the Ni–Mn–In ternary system at 773 K was investigated and constructed using X-ray diffraction (XRD), and electron probe microanalysis (EPMA) techniques. The existence of 7 binary compounds and 2 ternary compounds was confirmed in the isothermal section. The six binary compounds Ni2In3 (Ni2Al3-type structure, space group P3¯m1), NiIn (CoSn-type structure, space group P6/mmc), Ni13In9 (Ni13Ga9-type structure, space group C2/m), Ni2In (Co1.75Ge-type structure, space group P63/mmc), Ni3In (Mg3Cd-type structure, space group P63/mmc) and Mn3In (Al4Cu9-type structure, space group P4¯3m) in the sub-binary systems Ni–In and Mn–In are stoichiometric compounds, the homogeneity ranges of which are negligible. While the five single phase regions in the Ni–Mn binary system show a more or less homogeneity ranges formed by replacement of Mn for Ni. The homogeneity ranges of the ternary compounds T1 (Ni2MnIn) and T2 (Mn3Ni2In) at 773 K were determined.
