摘　　要：主要研究了TbxDy1-xFey(0.27≤x≤0.50,y≈1.95)退火合金粉末的近似单晶颗粒,在磁场中的取向情况,及其与成分x,颗粒的粒度,有机胶比,取向场,取向温度等之间的关系。观察到在x为0.295与0.33之间,取向效果有很大的差异。并对取向效果与上述各因素之间的关系进行了讨论。The orientation of approximate single-crystal particles of annealed alloy TbxDy1-xFey(0.27≤x≤0.50,y≈1.95),and the correlation between orientation and several factors such as the composition x,the particle size,the ratio of organic glue,the magnetic field and the temperature etc were presented.A great difference of the oriented results on composition between x≤0.295 and x≥0.33 was found.The correlation about the oriented result and each factor was discussed.
