研究了热处理弹簧钢 60Si2CrVAT 因负载阶梯式增长的三点弯曲而产生的疲劳抗力。采用扫描电镜方法对钢的显微组织和疲劳断口进行了分析。考虑提高高速货运转向架弹簧抗疲劳性能的可能性。
Fatigue resistance of heat-treated spring steel 60Si2CrVAT due to three-point bending with step growth in the load is studied. The microstructure of the steel and fatigue fracture surfaces are analyzed by the method of scanning electron microscopy. The possibilities of raising the fatigue resistance of springs used in high-speed freight bogies are considered.
