Mechanisms of Deformation in the Hot Working of Nickel-Base Superalloys

Abstract

The mechanisms of hot deformation have been determined to be dynamic: recovery and dynamic recrystallization which control the flow stress developed and the rate of crack propagation. Through their subsequent interaction with static recovery and static recrystallization, which occur whenever the metal remains hot after deformation, they also dete-rmine the structure and properties either upon cooling or at entrance to another stage of deformation.
