Explanation
heat treatment process to make materials structure balanced and even and bating. Generally, alloy is heated to high temperature for heat preservation and homogenization, and then cooled slowly to obtain balanced structure and eliminate residual stress. Iron and steel materials can be divided into two categories according to the difference of annealing heating temperature and annealing: ① annealing with heating and holding temperature higher than AH or Ae3, including diffusion annealing, full annealing and spheroidizing annealing annealing; ② annealing with heating and holding temperature lower than the critical temperature of Ad, including bating annealing, recrystallization annealing and stress-relief annealing.
