| Abstract: | Based on the metallurgical theories of welds,a modified cellular automaton(CA)and Monte Carlo(MC)model is constructed on microstructural evolution during welding solidification.The CA/MC scheme is used to the development of evolutional rule of grains nucleation and growth combined with finite difference calculation of thermal and solute diffusion.The model is employed to simulate the formation of welding solidification microstructure in low-carbon ferritic stainless steel.It is found that the simulation can... |
