Phase Stability of Three Fe–Mn–Al–Ni Superelastic Alloys with Different Al:Ni Ratios

نویسندگان

چکیده

Fe–Mn–Al–Ni superelastic alloy is a potential candidate for diverse engineering applications due to its outstanding properties and low material costs. Recent studies suggest that slight changes in the chemical composition severely affect response, phase stability grain growth kinetics. In this paper, we found Al stabilizes parent α at high temperature promotes formation of β precipitation lower temperature. An with 3:1 ratio between Ni produces homogeneously distributed precipitates fraction alpha matrix after quenching from 1200 °C. The presence these phase, lowers martensitic transformation gives fully-reversible stress-induced behaviour without need apply an aging step. alloys content produced during restricted pseudoelasticity impaired.
