摘　　要：在制备C19400-SiC复合材料过程中,SiC的成分难以控制,实验引入电磁搅拌的方法.实验结果表明,电磁搅拌技术促进了合金中SiC的添加,C19400-SiC复合材料的晶粒尺寸减小了40%.此外,采用电磁搅拌后,复合材料硬度略有提高,导电性能得到改善.It is difficult to control the composition of SiC in the process of preparing C19400-SiC composites.The electromagnetic stirring method is introduced in the experiment.The experimental results show that the electromagnetic stirring technology promotes the addition of SiC in the alloy,and the grain size of C19400-SiC composites is reduced by 40%.In addition,after using electromagnetic stirring,the hardness of the composite material is slightly increased,and the electrical conductivity is improved.
