Shape memory and associated properties in Fe–Mn–Si-based ribbons produced by melt-spinning

Four Fe–Mn–Si alloys, Fe62Mn32Si6, Fe62Mn20Si5Cr8Ni5, Fe62Mn16Si5Cr12Ni5 and Fe65Mn9Si7Cr10Ni9, were obtained by the melt-spinning method. The samples were structurally, magnetic and shape memory effect (SME) investigated, both “as quenched” and thermally treated. The Mn-rich compositions show different phase, magnetic behavior and SME in comparison with Mn-poor compositions. The thermal treatments generate transformation between the two existing majority phases (α and γ), related magnetization and SME behavior. The features are derived from the corroboration of structural, magnetic interaction and magnitude of SME data.
