Abstract
THE PROPOSAL CONCERNS THE IMPROVEMENT OF A CLASS OF HIGH-ENERGY PERMANENT MAGNETS NOW UNDER DEVELOPMENT; HEAT-BONDED COMPOSITES OF HARD MAGNETIC ALLOY POWDERS IN A DUCTILE METAL MATRIX. THE APPLICABILITY OF SN/PB-SOLDER BONDING TO IRON-NEODYMIUM-BORON ALLOYS WILL BE EXPERIMENTALLY EXPLORED. POWDERS OF DIFFERENT PARTICLE SIZES WILL BE PREPARED FROM PRE-SINTERED FE-ND-B, COMPACTS OF THESE WITH SOLDER POWDER ADDITIONS WILL BE MADE AND HEAT-BONDED BY IMMERSION IN A SOLDER BATH. THE QUALITY AT THE BOND WILL BE STUDIED METALLOGRAPHICALLY AND BY COMPRESSION TESTS. MAGNETIC PROPERTIES AND THEIR STABILITY AT ENVIRONMENTAL TEMPERATURES UP TO 150 DEGREES C WILL BE INVESTIGATED. AGING BEHAVIOR WILL BE COMPARED WITH THAT OF SINTERED FE-ND-B AND SMCO5, AND WITH POLYMER AND SOLDER-MATRIX MAGNETS MADE FROM SM-CO AND OTHER RARE EARTH-TRANSITION METAL ALLOYS.
