    摘要:

    建立并深入分析了3種表層淬火熱應(yīng)力模型和2種內(nèi)部淬火熱應(yīng)力模型及其實(shí)際應(yīng)用。同時(shí)建立了不發(fā)生淬火角端效應(yīng)時(shí)角端和邊緣的二維和三維淬火模型及其實(shí)際應(yīng)用。提出了淬火動(dòng)態(tài)薄膜效應(yīng)，按照有無(wú)動(dòng)態(tài)薄膜效應(yīng)歸類(lèi)分析了各種常見(jiàn)淬火介質(zhì)淬火熱應(yīng)力的分布形態(tài)并深入討論了淬火動(dòng)態(tài)薄膜效應(yīng)與淬火角端效應(yīng)之間的聯(lián)系與區(qū)別。

    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.
