利用同步辐射X射线衍射和透射电子显微镜研究了一种淬火配分钢中残余奥氏体的力学稳定性。结果发现，马氏体相变发生在高碳块状残留奥氏体在变形开始，而低碳膜状残留奥氏体，尽管具有低得多的碳含量，是稳定的应变高达12%。两种可能的机制来解释这些有趣的发现。
Synchrotron X-ray diffraction and transmission electron microscopy experiments are employed to investigate the mechanical stability of retained austenite in a quenching and partitioning steel. It is found that martensitic transformation takes place in high carbon blocky retained austenite at the onset of deformation, while low carbon film-like retained austenite, despite having a much lower carbon content, is stable at strains up to 12%. Two possible mechanisms are employed to explain these interesting findings.
