Research abstract

THE MAIN OBJECTIVE IS TO DETERMINE THE FEASIBILITY OF IMPROVING THE HIGH TEMPERATURE CHARACTERISTICS OF LOW COST FE-CO-ND-B MAGNETS SO THAT THEY MIGHT REPLACE EXPENSIVE SMCO5 MAGNETS IN NUMEROUS APPLICATION. WE PROPOSE TO MAGNETICALLY ANNEAL AMORPHOUS MELT-SPUN FE-CO-ND-B AT TEMPERATURES NEAR THE CRYSTALLIZATION IN ORDER TO INCREASE THEIR COERCIVITY. SINCE THE OPTIMUM MAGNETIC ANNEALING TEMPERATURE AND APPLIED FIELD VARY WITH COMPOSITION, WE WILL OPTIMIZE THOSE PARAMETERS FOR THE SYSTEM FE77-XCOXND15B8 WHERE X = 15,20,25,30,35,40,45,50,55,60). CURIE TEMPERATURE, ENERGY PRODUCT AND COERCIVITY WILL BE DETERMINED IN ORDER TO FIND THE COMPOSITION WITH THE BEST COMBINATION OF MAGNETIC PARAMETERS.
