Investigation of the Creep Age Forming Mechanism and Springback Behavior of LY12
we have studied the evolution characteristics of the second phase which was precipitated and analyzed the strengthening mechanism from the points of microscopic view. In the article we modified the constitutive equation of creep and developed ABAQUS/CREEP
simulated the aging time
aging temperature and prebending radius influencing on springback laws
establish unified springback simulation function. The feasibility of this method can be proved by comparing the calculated value and experimental value.
