Phase-field study for the pre-precipitation process of L12-Ni3Al phase in Ni–Al–V alloy
چکیده انگلیسی

The microscopic phase-field dynamic model is employed to study the pre-precipitation process of Ni–Al–V alloy. Our computer simulation results show that there exists pre-precipitated phase with L10 structure before L12 phase formed, temperature and elastic strain energy play significant effect on the pre-precipitated phase with L10 structure. The elastic strain energy can induce the formation of L10 pre-precipitated phase. Under the same temperature, the greater the elastic strain energy is, the easier L10 pre-precipitated phase will form; under the same elastic strain energy, with the temperature increasing, the incubation period and existent time of L10 pre-precipitate phase are prolonged, the number of L10 precipitated phase also increases, and the formation of the L12 phase are delayed.


► There exists pre-precipitated phase with L10 structure before L12 phase formed.
► The elastic strain energy can induce the formation of L10 pre-precipitated phase.
► Increasing the temperature, the incubation period of L10 pre-precipitate phase are prolonged.
► The pre-precipitated phase affects the precipitation process of L12-Ni3Al.
