Case Study 6: Crankshaft Oil Hole Cracking

Induction hardening of a crankshaft component has a cracking possibility at the oil hole locations. DANTE modeling was used to model the hardening process and obtain an in-depth understanding of the reason high, in-process stresses occur. The quench delay timing is optimized to reduce the magnitude of in-process tensile stresses.
