Effect of precision casting on metal structure and properties

The temperature limits that divide cold deformation and thermal deformation vary with the metal and alloy system. The physical basis for dividing the temperature is that the atomic self-diffusion rate is high in the case of thermal deformation, which is sufficient for recovery and recrystallization to counteract the deformation hardening effect. In the case of cold deformation, sufficient recrystallization does not occur. The following is specifically light-cold, metal structure after thermal deformation; and characteristics of performance changes. The first section, the microstructure and properties of the metal after cold deformation In the processing of metal products, the method of cold deformation is widely used.
