摘要

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.
