摘　　要：本文通过对BYR48软磁合金开展不同退火温度和不同升温速度的热处理工艺实验,掌握了热处理工艺调整对合金组织结构和磁性能的影响规律。结果表明,降低热处理退火温度有助于降低合金最大磁导率,使合金交流磁性能提高。同时,降低退火过程中的升温速度可以改善合金组织结构不均匀现象,使合金获得均一稳定的晶粒组织,提高合金性能稳定性。In this paper,the effect of heat treatment process adjustment on the microstructure and magnetic properties of BYR48 soft magnetic alloy were studied by conducting heat treatment process experiments at different annealing temperatures and heating rates.The results show that decreasing the annealing temperature is helpful to decrease the maximum magnetic permeability and improve the AC magnetic properties of the alloy.At the same time,reducing the heating rate during the annealing process can improve the uneven microstructure of the alloy,make the alloy getting uniform and stable grain structure,and improving the stability of the alloy properties.
