Abstract

Temperatures of phase transformations of a number of Ni2MnGa-based alloys (four compositions), which are characterized by substitution of nickel for manganese at an unchanged gallium content (25 at %), have been determined. As the nickel concentration increases with respect to the stoichiometric composition (or the electron concentration e/a increases), the liquidus (T liq), solidus (T sol), and martensitic transformation (T mart) temperatures increase, whereas the magnetic transformation temperature (T C) decreases slightly.
