摘　　要：日本住友金属成功地开发了一种资源节约型高强度无取向电工钢SXRC,这种电工钢是通过固溶铌适度抑制位错的合并对消而得到一种特殊的微观组织,因此兼具很高的力学性能和磁性,特别适用于HEV、EV驱动电机转子。而且,不使用昂贵的镍就可以达到期望的强度,合金成本可控,是一种优越的资源节约型产品。Sumitomo metal industries ltd of Japan successfully developed a type of high strength non-orientation electrical steel SXRC of resources-saving. The steel has both high mechanical performance and good magnetic property thanks to the special microstructure produced by the formation of Nb solid solution serving to appropri- ately inhibit the combination and cancellation of dislocations. The material is, in particular, suitable for manufac- turing rotors of HEV and EV driving motors. Besides, expected strength can be achieved without adding costly Ni and then the cost of alloy can be decreased. So the steel is a superior material of resources-saving.
