phase and equilibrium phase were analyzed. The simulation results indicate that nonstoichiometric L10 pre-precipitation phase formed first, and then would gradually transform into L12 equilibrium... was higher and interatomic potential was smaller than that of L12 equilibrium phase. Therefore, it is concluded that L10 phase was unstable, and phase transformation would occur to L12 which was more......
