RCo5(R=rare earth)sintered magnets have good temperature stability,so it is still widely used in high temperature field.In this paper,by the method of adding liquid phase SmCo1.7 to the main phase,Sm0.7Y0.3Co5 magnet was prepared by traditional powder metallurgical process.The results show the presence of a main phase RCo5,a minor phase R2 Co7,and a R-rich phase in the magnet.Contrasting the results of the XRD(X-ray diffraction)in random and oriented directions,the magnet has a well-aligned(00l)orientated texture,which is consistent with the result of the electron backscattered diffraction(EBSD).The Sm0.7Y0.3Co5 sintered magnet has good magnetic properties as remanence(Br)is 0.96 T,the coercivity(Hcj)is 1201.96 kA·m-1,and maximum magnetic energy product((BH)max)is 175.16 kJ m-3. 展开更多
