摘要:

建立并深入分析了3种表层淬火热应力模型和2种内部淬火热应力模型及其实际应用。同时建立了不发生淬火角端效应时角端和边缘的二维和三维淬火模型及其实际应用。提出了淬火动态薄膜效应，按照有无动态薄膜效应归类分析了各种常见淬火介质淬火热应力的分布形态并深入讨论了淬火动态薄膜效应与淬火角端效应之间的联系与区别。

Abstract:

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.
