The cooling rate from a high-temperature heat treatment is also a very important process parameter. As discussed for steels, slow cooling will yield ductile and tough pearlitic microstructures. Quenching will produce high-strength and low-toughnessmartensitic microstructuresthat may be tempered to produce...
2. Use reasonable cooling methods The cooling process after metal quenching is also an important cause of deformation. In the case of quenching, the deformation of hot oil quenching is smaller than that of cold oil quenching, generally controlled at 100 ± 20 ℃. The cooling ability of oil ...
