| 中文摘要 | The effects of the antiphase domain (APD) and the elastic energy on the morphology evolution of gamma' precipitates in Ni-Al binary alloy during aging process are studied with the phase-field method. The merging-splitting phenomenon between the two neighboring gamma' precipitates is observed. The changes of gamma' area fraction and average 7' size are analyzed for different APDs and for different elastic energies, respectively. It is shown that the merging-splitting phenomenon may occur when the radii of neighboring gamma' precipitates with different APDs are smaller than 24 nm and the critical size for the merged gamma' precipitate splitting is about 108 nm. Besides, the coarsening of gamma' precipitates is significantly impeded by the APDs but accelerated by the elastic energy, and the change of average gamma' size can be divided into two stages with different mechanisms.
