抄録

Electric resistance-temperature curves were traced with Ainico 5 magnet aged at various temperatures. The results suggest that different mechanisms of transformation may operate at about 600°C and at about 650°C. The former temperature corresponds to the aging temperature that gives the best magnetic characteristics, and the latter corresponds to anoth er aging temperature where the irreversible change in magnetic property occurs. The electric resistance-temperature curves of specimens aged at a temperatures over 650°C show a kink point meaning a precipitation, which disappears after 600°C re-aging. This re-aging also changed the inclination of the whole curve.
