MnAl alloy is most succesfully melted by high frequency induction furnace under argon atmosphere in alumina crucible. The alloy containing 68 to 70 wt% of Mn exhibits the highest saturation magnetization in this system. Ferromagnetic phase (π-phase) can be prepared by quenching and subsequent tempering. The adequate quenching temperature is 1100° to 1150°C. When quenched MnAl alloy is tempered at a temperature not exceeding 500°C, its saturation magnetization increases with time and approaches to a common limiting value. Higher the temperature is, more rapidly it reaches to the limit. For example, at 500°C, limiting value is realized within few tens of minuits. Although the specimen tempered at above 500°C losses its magnetic properties after a very rapid increasing in saturation magnetization, the peak value of it is rather higher than the limiting value in lower temperature tempering. X-ray diffraction and microstructure shows that the ferromagnetic phase thus obtained is entirely the same as what obtained through H. Kôno’s “controlled cooling”.
