文章亮点

(1) 系统地研究了随着回火温度的改变，DZ2车轴钢强度和韧性的变化趋势

(2) 用示波冲击的测试方法对DZ2材料冲击过程中能量消耗特点和趋势进行分析。

(3) 通过微观组织碳化物的特点分析了冲击功中裂纹扩展功的变化原因。

中文摘要

DZ2车轴钢是中国具有自主知识产权的高铁车轴材料，为满足严苛条件下的服役安全性，需要对其冲击韧性进行全面了解。与传统的夏比摆锤冲击试验方法相比，示波冲击试验有助于分析材料在冲击断裂过程中的具体力学行为。在本文中，对DZ2车轴钢在不同回火温度下的强度和韧性之间的倒置关系进行了测试和分析，并通过示波冲击的测试方法对DZ2车轴钢冲击过程中能量消耗特点和趋势进行分析。回火过程显著影响碳化物的析出行为，导致碳化物的长径比不同。通过对应力分布、示波冲击统计、断口形貌和碳化物形貌的综合分析，研究了冲击裂纹扩展过程的特征。冲击韧性随着回火温度的升高而提高，主要是由于冲击裂纹扩展所需能量的增加。低回火温度试样冲击韧性差的原因是，在扩展过程中，小塑性区的碳化物形态导致应力集中点数量增加，导致断口上脆性和韧性断裂混合分布。

Instrumented oscillographic study on impact toughness of an axle steel DZ2 with different tempering temperatures

Abstract

Abstract

Compared with the conventional Charpy impact test method, the oscillographic impact test can help in the behavioral analysis of materials during the fracture process. In this study, the trade-off relationship between the strength and toughness of a DZ2 axle steel at various tempering temperatures and the cause of the improvement in impact toughness was evaluated. The tempering process dramatically influenced carbide precipitation behavior, which resulted in different aspect ratios of carbides. Impact toughness improved along with the rise in tempering temperature mainly due to the increase in energy required in impact crack propagation. The characteristics of the impact crack propagation process were studied through a comprehensive analysis of stress distribution, oscilloscopic impact statistics, fracture morphology, and carbide morphology. The poor impact toughness of low-tempering-temperature specimens was attributed to the increased number of stress concentration points caused by carbide morphology in the small plastic zone during the propagation process, which resulted in a mixed distribution of brittle and ductile fractures on the fracture surface.
