采用光学显微镜、扫描电镜、能谱仪、透射电镜、拉伸试验、冲击试验、盐雾腐蚀试验和相分析试验等研究了低温(240℃)和高温(500℃)回火对N合金化耐蚀塑料模具钢组织与性能的影响。结果表明:试验钢的组织均主要为回火马氏体,均析出了M_(3)C型碳化物。高温回火后试验钢的位错上析出了纳米级的M(CN)型碳氮化物以及M_(23)C_(6)碳化物,表明回火温度的升高可以促进氮化物的析出。低温回火和高温回火后试验钢的冲击吸收能量分别为32.4 J和10.4 J,断后伸长率变化不大,但是高温回火后试验钢的屈服强度与抗拉强度略有提升,并且大量碳氮化物在位错形核,增加了试验钢的解理断裂倾向。试验钢的腐蚀形式主要为点蚀,其低温回火后的耐腐蚀性远大于高温回火,腐蚀速率分别为0.005 g/(m^(2)·h)和0.026 g/(m^(2)·h);低温回火与高温回火后试验钢的自腐蚀电位分别为-0.08 V和-0.125 V,且后者的钝化膜极易破裂,这是由于在高温回火过程中,高合金含量的碳化物大量析出,且大多为富铬的M_(3)C或M_(23)C_(6)型碳化物,从而形成较多贫铬区,导致试验钢的耐腐蚀性能降低。

Martensitic stainless steel containing Cr of 12% to 18%（mass percent） are common utilized in quenching and tempering processes for knife and cutlery steel. The properties obtained in these materials are significantly influ- enced by matrix composition after heat treatment, especially as Cr and C content. Comprehensive considered the hardness and corrosion resistance, a new type martensitic stainless steel 6Crl5MoV has been developed. The effect of heat treatment processes on microstructure and mechanical properties of 6Crl5MoV martensitic stainless steel is emphatically researched. Thermo-Calc software has been carried out to thermodynamic calculation; OM, SEM and TEM have been carried out to microstructure observation; hardness and impact toughness test have been carried out to evaluate the mechanical properties. Results show that the equilibrium carbide in 6Cr15MoV steel is M23 C6 car- bide, and the M23 C6 carbides finely distributed in annealed microstructure. 6Crl5MoV martensitic stainless steel has a wider quenching temperature range, the hardness value of steel 6Cr15MoV can reach to HRC 60.8 to HRC 61.6 when quenched at 1 060 to 1 100 ℃. Finely distributed carbides will exist in quenched microstructure, and effectively inhabit the growth of austenite grain. With the increasing of quenching temperature, the volume fraction of undis- solved carbides will decrease. The excellent comprehensive mechanical properties can be obtained by quenched at 1 060 to 1 100℃ with tempered at 100 to 150 ℃, and it is mainly due to the high carbon martensite and fine grain size. At these temperature ranges, the hardness will retain about HRC 59.2 to HRC 61.6 and the Charpy U-notch impact toughness will retain about 17.3 to 20 J. A lot of M23C6 carbides precipitated from martensite matrix, at the same time along the boundaries of martensite lathes which leading to the decrease of impact toughness when tempered at 500 to 540 ℃. The MaC precipitants also existed in the martensite mat
