摘要: 利用TEM和X射线衍射仪对固溶态、固溶空冷态和固溶冰水淬火态亚稳奥氏体Fe-12Cr-10Mn(W,V)合金(84),以及固溶态、固溶+拉伸变形态稳定奥氏体Fe-13Cr-17Mn(W,V)合金(85N)中γ→ε转变与层错之间的关系进行了研究,并对影响γ→ε马氏体转变的合金元素进行了分析,提出了进一步提高合金相稳定性的措施。Abstract: The characteristics of γ→ε transformation and stacking faults in the sub-stability Fe-12Cr-10Mn(W,V) alloy (84) after solution-treated followed by cooling in air and by quenching into ice water and these in the phase stability Fe-13Cr-17Mn(W,V) alloy (85N) after solution-treated followed by water, solution-treated followed by deformation were investigated by transmission electron microscope (TEM) and X-ray diffraction. Some ways to increase the phase stability were also carried out through analyzing the influence of some elements on the transformation of γ→ε.
