评述了一系列高Ｃｏ－Ｎｉ二次硬化马氏体钢的合金设计、热处理工艺以及显微组织对力学性能的影响，并探讨了在韧性和塑性损失较小的情况下，进一步提高这类钢的强度的可能性。
The effects of alloy design, heat treatment process and microstructure on the mechanical properties of a series of high Co-Ni secondary-hardenable martensitic steels were reviewed. It was also discussed that this type of steels could be further improved with less loss of ductility and ductility The possibility of strength.
