Challenges to Introduce Advanced Cooling Technology by the Utilization of Plural Cooling Velocity Kiyoshi Funatani1 (1.IMST Inst, Nagoya JAPAN) 摘要:The control of cooling power is very important to introduce desired properties. Usually, higher the cooling rate higher the quench hardness and distortion and the optimization of cooling power is the base for good heat treatment. The change......
