Abstract—

Rapidly quenched Mn₅₅Al₃₆Ga₉ ribbons have been obtained using a spinning method. In the initial quenched state, the ribbon structure is a two-phase one consisting 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 min. This work describes both the phase composition obtained as a result of annealing at different temperatures and the features of the microstructure studied via electron microscopy.
