Mechanical alloying of Mn-30at.% Al powder mixture resulted in the formation of an α-Mn solid solution in the early stage of milling with the subsequent formation of β-Mn phase after 30h milling.Thermal treatment at 1060 0 C, confirmed the recently extension of the high temperature ε-phase.However, the presence of impurity atoms, mainly iron, impeded the expected ε→β transformation during quenchin...
