- 摘要:
- 通过对不同工艺生产的E级钢钩舌实物性能指标、显微组织的分析及对比,研究钩舌的疲劳性能。指出了成分和热处理方式对钩舌疲劳性能的影响,为提高钩舌综合力学性能提供了研究方向。The fatigue properties of coupler hook tongue were studied by analyzing and comparing performance and microstructure of E-grade coupler hook tongues which produced by different processes.The effects of composition and heat treatment on the fatigue performance of the hook tongues were pointed out,which provided a research direction for improving the comprehensive mechanical properties of the hook tongue.
