摘要：
With the development of nucleation theory, the calculation of phase diagrams(CALPHAD) method and microscopic elasto-plasticity mechanics, it is possible to apply the phase-field method to simulate the gamma ' rafting behavior of nickel-base single-crystal superalloys under the conditions of heat treatment, fatigue and creep testing. Based on the experimental progress in gamma ' rafting behavior and in combination with the microstructural simulation of the precipitation and rafting of gamma ' phase, this paper reviews the phase-field investigation of gamma ' rafting in nickel-base single-crystal superalloys.
