Abstract
Through quenching is applied for giving desired mechanical properties of manufactured engine sling adapter. Quenching technique i.e. still and stir cooling into tap water is designed for this hardening process. Computer simulation code of DEFORM-HT was used before experiment to determine optimum process parameter and to predict mechanical properties and distortion of the hardened past. By employing single heat transfer coefficient (HTC) taken from still and stirred-quenched JIS silver probe, more distorted adapter is produced under still quenching than that under stir quenching. Comparison between simulation and experiment is presented. However, zone-based surface HTC is then needed to give more accurate prediction.
