AbstractNi–Fe–Ga-based alloys form a new class of Ferromagnetic Shape Memory Alloys. The problem of brittleness of the Ni-Mn-Gabased alloys can largely be overcome in case of Ni–Fe–Ga-based ones by introducing a disordered fcc γ-phase. The current study explores thermo-mechanical processing of this alloy using an off-stoichiometric Ni55Fe19Ga26 alloy containing the ductile γ-phase. Hot-rolling of Ni55Fe19Ga26 alloy was carried out at 950∘C and 1000∘C, both with and without mild steel jacket. The microstructure of the hot-rolled products was analyzed in detail. Microtexture analyses were carried out both for the L21 and the γ-phase independently using Electron Back-Scattered Diffraction technique.
