Abstract Based on the goal of creep age forming 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.
