摘要:

以核电站环形起重机用42CrMo耐热钢为研究对象, 分析了显微组织中碳化物形貌和分布随回火温度的变化及其对冲击韧性的影响.结果表明, 42CrMo钢经水淬后在500-650 ℃区间回火, 显微组织均为回火索氏体.随回火温度上升, -12 ℃冲击功先增加后减小; 经500和530 ℃回火后, 片状碳化物不均匀分布于原马氏体板条界上, 冲击功分别为26和44 J; 600 ℃回火后碳化物呈颗粒状弥散分布, 冲击功达到峰值104 J; 600 ℃以上回火, 颗粒状碳化物明显粗化,冲击功下降.碳化物的形貌和分布是影响42CrMo钢冲击性能的关键因素.

Abstract：

42CrMo heat–resistant steel is a kind of structural steel, which is widely used in structural components such as crane weight–on–wheel, automobile crank shaft, locomotive gear hub and so on, for its good hardening ability, high temperature strength, good creep resistance, and little quenching deformation. However, in industry application, mismatching between the strength and the toughness always occurs for 42CrMo structure components. In order to solve the problem that the strength does not match the toughness in the manufacturing process for the polar crane for the nuclear power station, the effect of tempering temperature on the morphology and distribution of carbides and the impact toughness has been investigated for steel 42CrMo in this study. The experimental results indicated that the microstructure of the quenched steel 42CrMo after 500—650 ℃ tempering was characterized by tempering sorbite. As the tempering temperature increased, the Charpy absorbed energy at –12℃ initially increased and then decreased. The flake carbides after 500 and 530 ℃ tempering are not evenly distributed on the original martensite boundaries, the Charpy absorbed energy are 26 and 44 J, respectively. While the granular carbides are evenly distributed in the microstructure after 600℃ tempering, the Charpy absorbed energy reaches a maximum value of 104 J. When the tempering temperature is higher than 600 ℃, granular carbides coarsened obviously and the Charpy absorbed energy reduced notably. The morphology and distribution of carbides is the key factor that influences the impact toughness of steel 42CrMo. Morphology and structure analysis for the carbide was carried out by TEM together with EDS analysis, the results showed that the carbide after tempering treatment is (Fe, M)3C and Fe, Cr, Mo are the main alloy element in the carbide. When the tempering temperature is in the range of 560—600 ℃, the uniformly–distributed granular carides forms on the matrix and the impact toughness is over 60 J. As the tempering temperature continues increasing, the carbides will coarsen and the impact toughness will decrease. In order to obtain the good strength and toughness matching, for 42CrMo structure, it is recommended that the tempering temperature should be in the range of 550—590 ℃.
