摘　　要：在热处理过程中,对非晶软磁合金施加定向磁场或应力可以使其产生定向的轴向磁各向异性,这类轴向磁各向异性可以提高非晶软磁合金在特定方向上的软磁性能,尤其对提高磁导率有着显著作用.以Co80Fe5Mo2Si10B3非晶合金条带为研究对象,测定居里温度,并在近居里温度研究拉应力退火对软磁性能的影响:退火温度240℃,拉应力0~350 MPa,保温时间30~120 min.结果表明:近居里温度拉应力退火可以有效提升合金的软磁性能,并且随着保温时间的增加,最大磁导率μm随之升高.Uniaxial magnetic anisotropy can be induced by directional magnetic field or stress during annealing,and the magnetic properties especially the permeability in the uniaxial direction of the soft magnetic alloys can be improved by the uniaxial magnetic anisotropy.The curie temperature of Co 80 Fe 5Mo 2Si 10 B 3 has been measured and the tensile stress annealing process at the near curie temperature has been researched.The annealing temperature is 240℃,the tensile stress 0~350 MPa,and the annealing time 30~120 min.The results indicate that the soft magnetic properties has been improved significantly,andμm has been improved with the increase of the annealing time after the tensile stress annealing at near curie temperature.
