为克服因滚动接触疲劳(RCF)引起的各种钢轨缺陷,铁路线路管理维护部门每年需要投入大量资金对钢轨进行打磨修理。随着运量的不断增加,车轮与钢轨之间成千上万次相互作用,造成钢轨应力加剧,从而产生滚动接触疲劳。2000年发生在英国Hatfield的列车严重脱轨就是因钢轨滚动接触疲劳造成的。Voestalpine公司在2005年左右,就认识到市场需要一种新型的钢,利用这种钢制造的钢轨可以完
In order to overcome various rail defects caused by rolling contact fatigue (RCF), the railway line maintenance department needs to spend a lot of money to repair and repair the rails every year. As the volume increases, tens of thousands of interactions between the wheel and the rail cause rail stress to intensify, resulting in rolling contact fatigue. A serious derailment of a train that took place in Hatfield, England, in 2000 was caused by rolling contact fatigue of the rail. Around 2005, Voestalpine realized that the market needed a new type of steel that could be finished with rails made of this steel
