Microstructures and magnetic properties of Sm(CobalFe0.245Cu0.07Zr0.02)7.8 sintered magnet solution-treated at high temperature
文献摘要：
Sm(CoFeCuZr)z sintered permanent magnet has been attracting a great deal of attention by virtue of its high-temperature magnetic properties,low temperature coefficient and good corrosion and oxidation resistance.The microstructures and magnetic properties of Sm(CobalFe0.245Cu0.07Zr0.02)7.8 sintered permanent magnet prepared by a traditional powder metallurgy method were investigated.Tunable magnetic properties,especially the maximum magnetic energy product,(BH)max,were obtained through adjusting solution-treated temperatures.With solution-treated temperature increasing from 1155 to 1195℃,remanence(Br)almost keeps constant and knee point coercivity(Hk),magnetic induction coercivity(Hcb)and(BH)max first increase and then decrease.The intrinsic coercivity(Hcj)of magnet solution-treated at 1195℃is 738 kA·m-1,which is less than 2/5 that of magnet solu-tion-treated at 1183℃(＞1927 kA·m-1).The reason that magnet solution-treated at 1195℃shows lower Hcj than magnet solution-treated at 1183℃is considered to be mainly related to the fact that there are a lot of cells with abnormally small size.In addition,the lattice constant of Sm(CobalFe0.245Cu0.07Zr0.02)7.8 sintered permanent magnet solution-treated at 1195℃,given by indexing high-resolution transition electron microscope(HRTEM)results,is considered to be related to the formation of cells with abnormally small size which decreases Hcj.
