METALLOGRAPHIC EXAMINATION OF CRACKED WHEEL FLANGES FROM FAST

A major cause for condemnation of wheels at the Facility for Accelerated Service Testing has been flange cracking which developed in both cast and forged wheels with a higher incidence occuring in untreated and One-Wear type wheels and comparatively less in rim treated and Two-Wear types. The cracks nucleate beneath the surface in a region which has been plastically deformed and work hardened in the course of deformation. The phenomenon is identified as rolling contact fatigue similar to tread shelling. Wheel rail contact should be minimized near the flange apex.
