Abstract
Established a dynamic model of recrystallization dislocation, proposed MC algorithm simulation describing grain growth behaviors that can explain VSR eliminate component residual stress mechanism from the micro, which can provide an intuitive visualization. Used MATLAB programming grain growth of the grain in the different MC steps simulate images, to discuss the grain size distribution and the energy change in different MC steps, while compared the simulation results with the existing sample dislocation configuration electron microscopy photos around the VSR. It reflects the same trend, which can show that the MC method in numerical simulation of grain growth can fully reflect component microstructure evolution around VSR. Micro explains the VSR mechanism of residual stress relief member which provides intuitive visual basis.
