【摘要】用熔体快淬和晶化处理的方法制备了Nd2 (FeGaCo) 14 B/α Fe纳米复合材料 ,研究了晶化热处理温度和时间对材料磁性能的影响。结果表明Nd8Fe84 5Ga1Co2 B4 5纳米复合材料的磁性能随热处理条件而变化 ,低温长时间和高温短时间热处理所得样品的最佳磁性能相当更多还原

【Abstract】 The effect of annealing temperature on magnetic property for Nd 8Fe 84 5 Ga 1Co 2B 4 5 nanocomposite material prepared by melt spinning was studied The result shows that the magnetic property of Nd 8Fe 84 5 Ga 1Co 2B 4 5 nanocomposite magnet varies with the heat treatment conditions The same optimal magnetic property of the ribbon annealed at higher and lower temperature was found The reasons were discussed here更多还原
