  • Abstract:Computer simulation of induction heat treating processes is relatively widespread within the industry. The bulk of the simulation studies considered coupling two of the multiple phenomena that occur during the process: 1) the electromagnetic and thermal process, and 2) the metallurgical and thermal-stress process. Recent studies have incorporated more of the mutually coupled phenomena into the simulation process. In these studies, electromagnetic, thermal, metallurgical, stress and shape change were coupled together using multiple programs. These studies enhanced our capabilities to predict the actual part performance of induction hardening process. This paper describes a study of a complex induction hardening process of a full-float truck axle. The process includes a dwell heating of the flange and a scan hardening of the shaft and spline. Computer simulation of electromagnetic and thermal processes was made using Flux software. The power densities from Flux are then exported and mapped into the DANTE for thermal, metallurgical, stress and distortion simulation. The study is based upon component test data from Dana Corporation.
