Forging microstructure on performance of final heat treatment and effect
Forging production is metallurgy (raw materials) and the intermediate process between the final heat treatment, so the quality of after the final heat treatment of forgings quality and the use of spare parts has a big performance impact. Normal through heat treatment of forgings organization, of the Organization and the performance can be obtained. However, due to some improper forging process defects or raw materials left over from some of the flaws, has a great influence on the quality of heat treatment of forgings. Are illustrated as follows: some forging defects, in the after forged heat treatment can be improved, organizations could be obtained after the final heat treatment of forgings and performance. Such as: structural steel forgings for General overheating of coarse grain and Wei's body, eutectoid and bearing steel carbide slightly due to improper cooling.
