Experimental Investigation on Fatigue Crack Propagation in Surface-Hardened Layer of High-Speed Train Axles
This study examines fatigue crack growth behavior in induction-hardened S38C axle steel with a gradient microstructure. High-frequency three-point bending fatigue tests were conducted to evaluate crack growth rates (d<i>a</i>/d<i>N</i>) across three depth-defined regions: a hardened layer, a heterog...
