Summary: Heat-treaters have long relied on experience to assess the impact of steel chemistry and part shape on distortion and residual stress due to quench hardening. Using DANTE®, the residual stress and distortion response of a heat-treated disk was examined. The effect of several geometrical features (shoulder, disk thickness and center hole) was modeled, as well as the effect of several quenching variables. In addition, the impact of a carburized case on the disk distortion and stress state was also examined.
