Abstract:

According to the finite difference method and thermal elastic-plastic theory, combining with martensitic phase transformation kinetics and considering the latent heat and microstructure stress, the temperature, microstructure, stress and strain fields are analyzed. The research indicates that at the beginning of cooling, there are great temperature differences in the direction of thickness and width; at the end of cooling, the temperature and microstructure fields become homogeneous, but the stress and strain field is seriously inhomogeneous. A larger plastic strain occurs on the surface and distributes inhomogeneously in the direction of width are the basic reasons of residual stress. A theoretical basis is provided for improving the offline heat treatment process by analyzing the reason of bad flatness.
