Theoretical Models of the Thermal Stress Evolution Mechanism during Quenching of No Phase Transformation Alloy--(2) The Surface and Center Model for Thermal Stress during Quenching and the Dynamic Film Effect during Quenching

In this paper, 3 types of surface modes and 2 types of center modes and their practical applications were proposed and analyzed for the thermal stress analysis during quenching for no phase transformation alloy. And the 2D and 3D boundary and comer models without corner effect and their practical applications during quenching were also established and analyzed. The dynamic film effect, the phenomenon of dynamic wave of fathom line vs temperature, temperature gradient, thermal stresses and shape of plastic deformation zone were proposed. Also the thermal stress distribution, important to the technology, was analyzed with/without consideration of dynamic film effect. The relationship between the dynamic film effect and the comer effect during quenching was also analyzed.
