抄録

This study deals with the improvement of Magnetic properties of Mn-Al Magnet. 72 wt%Mn-Al alloys to which 0.5∼16 wt%B, Mo, Se, Te, W, and Zr were added, were prepared by means of melting in Argon atmosphere. Magnetic properties were measured on the specimens water-quenched from 1100°C, and subsequently tempered at the temperatures of 250° to 600°C for 2 hrs.<BR>The remarkable improvements in magnetic properties were found by the addition of B, Te, and Zr. Especially by the addition of B, some interesting phenomena were observed: A considerable amount of ferromagnetic phase appeared at the water quenched state, and the hysteresis loop showed a snaky form.<BR>In the microscopic observation, a needle shape compound appeared as the secondary phase in the alloys containing B.
