摘要: 利用TEM和X射線衍射儀對固溶態、固溶空冷態和固溶冰水淬火態亞穩奧氏體Fe-12Cr-10Mn(W,V)合金(84),以及固溶態、固溶+拉伸變形態穩定奧氏體Fe-13Cr-17Mn(W,V)合金(85N)中γ→ε轉變與層錯之間的關系進行了研究,并對影響γ→ε馬氏體轉變的合金元素進行了分析,提出了進一步提高合金相穩定性的措施。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.
