摘要/Abstract

摘要： 采用真空熔炼炉对某2∶17H型高性能SmCo合金进行熔炼,研究了烧结温度分别为1195、1200、1205、1210 ℃时对该合金的烧结态磁体磁性能和微观结构的影响。然后对4种烧结温度的永磁体进行磁性能和密度测试,并对其进行微观结构的表征。结果表明,适当的增加烧结温度,可使烧结态磁体的各项磁性能增加,但烧结温度过高,会使烧结态磁体的各项磁性能大大降低。当烧结温度为1205 ℃时得到最好的磁性能,其中剩磁B_r为11.41 kGs,内禀矫顽力H_cj为1.05 kOe,最大磁能积(BH)_max为7.365 MGOe。各项磁性能分别受烧结态磁体的元素分布、晶粒均匀性及尺寸、磁体密度、Sm₂O₃、富Zr相影响。

Abstract: A 2∶17H type high-performance SmCo alloy was smelted in vacuum melting furnace. The effect of sintering temperatures of 1195, 1200, 1205, and 1210 ℃ on the magnetic properties and microstructure of the alloy magnets was studied. Then, the density and magnetic properties of the magnets with four sintering temperatures were tested, and the microstructure was characterized. The results show that the magnetic properties of the sintered magnets increase with the increasing sintering temperature appropriately, but greatly reduced due to excessively high sintering temperature. When the sintering temperature is 1205 ℃, the sintered magnet has the best comprehensive magnetic properties, with B_r of 11.41 kGs, H_cj of 1.05 kOe, (BH)_max of 7.365 MGOe. The magnetic properties of sintered magnets are affected by the element distribution, grain uniformity and size, magnet density, Sm₂O₃phase, and Zr-rich phase, respectively.

Key words: 2∶17H type high performance SmCo alloy, sintered magnet, sintering temperature, magnetic properties, microstructure
