Features of Phase Composition and Structure of Rapidly Quenched Ferromagnetic Mn–Al–Ga Alloy
Year: 2024
Type: article
Abstract: Rapidly quenched Mn55Al36Ga9 ribbons were obtained by the spinning method. In the initial quenched state, the ribbons had a two-phase structure of the ε and γ2-phases. It has been established that, upon heating, the alloy undergoes a series of phase transformations, including the precipitation of the equilibrium β-Mn phase and its subsequent dissolution, the formation of the ferromagnetic τ-phase from both the ε and γ2-phases. The largest amount of the τ-phase was obtained by annealing at a temperature of 700 °C for 20 minutes. The work describes both the phase composition obtained as a result of annealing at different temperatures and the features of the microstructure studied by electron microscopy.
