摘自冶金部钢铁研究总院研究生聂武德的硕士学位论文,导师:廖乾初 长期以来,轨/轮表面损伤及其对策一直是铁道用钢的基本研究课题。由于影响轨轮系统磨损过程的因素很复杂,它包括运行参数,轨/轮接触参数,材料参数、表面环境状态参数等,因此必须对上述影响轨轮系统磨损过程的参数进行有选择地人工控制而加以单独研究。本文针对与轨轮系统磨损试验有关的几个研究方法进行了探索性的研究。1)根据再结晶与形变量的关系,测量了钢轨磨损表面的塑性
From the Institute of Iron and Steel Research Institute Nie Wude master’s degree thesis, instructor: Liao Qianchu For a long time, rail / wheel surface damage and its countermeasures has been the basic research topic of railway steel. Due to the complexity of the factors affecting the abrasion of the rail system, it includes the operating parameters, the rail / wheel contact parameters, the material parameters, the surface environmental condition parameters, etc. Therefore, the above parameters that affect the wear process of the rail system must be selectively and manually controlled And to be studied separately. In this paper, some research methods related to rail wear test are explored. 1) According to the relationship between recrystallization and deformation, the plasticity of rail wear surface was measured
