摘要：
An investigation of the effect of low-temperature annealings at 150-600 degree C on the coercitive force of powder metallurgy magnets of the type, Nd//0//. //5Pr//0//. //2//5Sm//0//. //2//5Co//5 (alloy 1) and Nd//0//. //5Sm//0//. //5Co//5 (alloy 2), is carried out. It is found that prolonged heat treatment of these magnets leads to structural and phase transformations in the main matrix which have a strong effect on the magnitude of the coercitive force of the magnets. Given a certain combination of temperature and of the time of low-temperature annealings, it is possible to attain a significant increase of the coercitive force by 30-40%.
