    摘要
  • 摘要: 從材料的晶體結構出發,研究了雙相不銹鋼超塑性變形的機理.利用背散射電子衍射花樣分析系統(EBSD),獲得了雙相不銹鋼變形過程中的ODF圖、極圖和取向與轉軸分布等晶體取向分布規律.結合透射電鏡對微觀組織的觀察結果進行了綜合分析.研究表明,雙相不銹鋼超塑性變形的機理為形變誘導析出和動態再結晶、晶界滑移以及變形中的晶粒轉動.

     

    Abstract: The superplasticity mechanism of duplex stainless steels was studied mainly by means of crystallography. On this basis, the Electron Back Scatter Diffraction (EBSD) system was used to obtain the orientation distribution, Tango-mapping and Mambo-pole figures. Microstructural studies associated with transmission electron micrographs observed in the specimens during superplastic deformation suggest that superplastic process occurs mainly by strain-induced phase transformation and dynamic recrystallization, grain boundary sliding and grain re-orientation mechanism.
