results of heat treatment processes.However, these results were insufficient to predict crack generation clearly because the mechanism relates not only to stress distributions in the parts but also... were simulated for considering a cause of the crack generation. Lastly a tentative plan was made for the future research. 关键词:Quench Cracking; Heat Treatment Simulation; [全文内容正在添加中] ......
