Abstract

A phase equilibrium analysis was carried out for the Ni–Mn–Ga–Sb and Ni–Mn–In–Sb systems in the absence of melt. Using topological modeling based on concentration diagrams of the ternary systems Ni–Mn–Sb, Ni–Mn–Ga, Ni–Mn–In, Ni–Ga–Sb, Ni–In–Sb, Mn–Ga–Sb, Mn–In–Sb, and fragmentary experimental data on phase equilibria involving Heusler intermetallics Ni2Mn1+x(Ga,Sb)1–x and Ni2Mn1+x(In,Sb)1–x, isobaric-isothermal subsolidus concentration diagrams of the quaternary systems Ni–Mn–Ga–Sb and Ni–Mn–In–Sb were constructed. The key differences between them are demonstrated.
