- W1242034296 abstract "在富稀土辅合金中添加Co,Nb,Ti,Ga,Al等元素,用双合金工艺制备一系列不同辅合金含量的烧结Nd-Fe-B磁体,对力学性能进行系统研究。结果表明,在主合金（NdDyTb）12.69（FeCoNb）84.01B6.00的基础上添加3.0wt%的（NdDyTb）25（FeCoNbTiGaAl）68B7富稀土辅合金,其抗弯强度从316MPa提高到344MPa,抗弯强度的改善来自于边界结构的改善以及一些新相的生成。当辅合金含量达到8wt%,合金的强度又下降为321MPa。还研究了热处理工艺对Nd-Fe-B永磁材料力学性能的影响,含3.0wt%辅合金的磁体抗弯强度由烧结态的291MPa提高到最佳回火态的344MPa,又下降为非最佳回火态的304MPa。" @default.
