..., spinning, stretch forming, and press brake forming. Since the hot forming range (925 to 1260 °C, or 1700 to 2300 °F) is high and rather narrow, cold forming with intermediate anneals is preferred for thin sheets. During cold forming operations, superalloys work harden rapidly. The rate of work hardening...
