摘要/Abstract

摘要： 对40Cr15Mo2VN高氮不锈轴承钢进行1060 ℃淬火及不同温度(160~560 ℃)回火处理,研究了回火温度对该钢显微组织、碳化物分布、硬度以及耐腐蚀性能的影响。结果表明,在160~360 ℃回火温度范围内,组织为回火马氏体及弥散分布的碳化物,当回火温度处于410~510 ℃时,组织表现为回火屈氏体,继续升高回火温度至560 ℃时,组织为回火索氏体。碳化物粒径均大多处于0~1 μm之间,回火温度低于360 ℃时,粒径小于2 μm的碳化物数量随温度升高逐渐增加,继续升高回火温度,小尺寸碳化物逐渐聚集形成超过5 μm以上的碳化物颗粒。随回火温度的升高,硬度先降低后升高再降低,而耐腐蚀性则逐渐降低,且盐雾腐蚀失重率与回火温度呈指数关系。

Abstract: 40Cr15Mo2VN high nitrogen stainless bearing steel was vacuum quenched at 1060 ℃ and then tempered at different temperatures (160-560 ℃). The effect of tempering temperature on microstructure, carbide distribution, hardness, and corrosion resistance of the 40Cr15Mo2VN high nitrogen stainless bearing steel was investigated. The results show that within the tempering temperature range of 160-360 ℃, the microstructure is tempered martensite and dispersed carbides. When the tempering temperature is between 410 ℃ and 510 ℃, the microstructure shows tempered troostite. When the tempering temperature is increased to 560 ℃, the microstructure is tempered sorbite. The particle size of carbides on the matrix mostly ranges from 0 to 1 μm. Below 360 ℃, as the tempering temperature increases, the number of carbides with particle size of less than 2 μm gradually increases. As the tempering temperature continues to increase, small-sized carbides gradually aggregate to form carbide particles exceeding 5 μm. As the tempering temperature increases, the hardness first decreases, then increases, and finally decreases again, while the corrosion resistance gradually decreases, and salt spray corrosion mass loss rate increases exponentially with the tempering temperature.

Key words: high nitrogen steel, tempering temperature, microstructure, hardness, corrosion resistance
