AbstractA synchronous improvement of the strength and plasticity (SISP) is a significantly important subject attracted by many researchers. In this study, the key factors affecting the plasticity and strength of spring steels were analyzed and discussed in detail. Meanwhile, the differences in the microstructures and fractographies between two Cr & ndash;Mn steels were compared. It is found that the 50CrMnSiVNb spring steel has higher strength as a result of the dislocation strengthening, the solution strengthening caused by the Si solid solution as well as higher workhardening capacity by comparing four strengthening mechanisms and work-hardening capacity. Furthermore, the better plasticity of the 50CrMnSiVNb steel may be mainly attributed to the lighter banded segregation and hydrogen embrittlement compared with the 50CrMnMoVNb steel. This study may enrich the fundamental knowledge regarding how to optimize the composition of spring steel and provide some new ideas for synchronous improvement of the strength and plasticity of spring steels.
