Abstract
THIS PROJECT CONCERNS A UNIQUE APPROACH TO THE PRODUCTION OFHIGH ENERGY PRODUCT MAGNETS EMPLOYING RAPID SOLIDIFICATION METHODS. RIBBONS OF RARE EARTH-COBALT ALLOYS ARE RAPIDLY SOLIDIFIED TO PRODUCE A MICRON-SIZED COLUMNAR MICROSTRUCTUREAND THE COERCIVE FORCE DURING MAGNETIZATION IS CONTROLLED BY DOMAIN NUCLEATION MECHANISM. THIS EFFORT PRODUCES HIGH- CURIE-POINT, HIGH-ENERGY-PRODUCT PERMANENT MAGNETS WITH REDUCED TEMPERATURE DEPENDENCE OF THE MAGNETIZING FIELD. THIS PROGRAM IS BASED ON ESTABLISHED TECHNOLOGIES, FOR EXAMPLE, THE PLANAR FLOW CASTING PROCESS WHICH PRODUCES UNIFORMLY QUENCHED RIBBONS AND ESTABLISHED FEATURES OF THE SM-CO ALLOYS.
