摘要
本文对速凝铸造工艺制备的钕铁硼母合金速凝带进行等温热处理 ,实验表明 ,热处理后的速凝带母合金组织结构发生变化 ,出现富钕相团聚 ,细小的片状晶融合长大。在 90 0℃左右对速凝带进行热处理 ,可以获得较好的磁性能。
Study of the effect of annealing strip cast alloys at different annealing temperature on sintered NdFeB magnets properties and microstructures of strip cast alloys is presented After isothermal annealing,microstructures of strip cast alloys are changed,the rich Nd phase get together,and fine sheet grains are merged together The magnetic properties of sintered NdFeB magnets prepared by isothermal annealing strip cast alloys at about 900℃ are apparently improved
