COMPATIBILITY OF THE PRODUCTION OF SM-CO AND ND-FE-B MAGNETS

Compatibility of the production of sintered permanent magnets from two different hard magnetic materials based on SmCo5 and Nd2Fe14B interme tallic compounds is considered. The effect of one alloy introduced as impurity on the fundamental magnetic properties, hysteresis characteri stics. and optimal production parameters of the magnets from the other alloy are studied. Suggestions about the relative contributions of th e alloy components into hysteresis properties, the relative effects of the alloys under study on phase compositions of sintered magnets and on fundamental magnetic properties (constants of anisotropy, saturatio n magnetization. and Curie temperature) of the main hard magnetic phas es (RT(5), R(2)T(14)B) are based on the analysis of the R-T and R- T-B equilibrium phase diagrams and the results obtained.
