利用同步辐射Ｘ光测量了Ｆｅ－Ｍｎ－Ａｌ－Ｃｒ合金的ＭｎｌｓＮＥＸＡＦＳ谱，多重散射团簇（ＭＳＣ）理论分析显示合金基体中的Ｍｎ和Ｆｅ分别以体心立方和面心立方微晶的形态存在，它们之间的耦合保证了合金是一种稳定的奥氏体钢．
The MnlsNEXAFS spectra of Fe-Mn-Al-Cr alloy were measured by synchrotron radiation X-ray. Theoretical analysis of multiple scattering clusters (MSC) showed that Mn and Fe in the alloy matrix were present in the form of body-centered cubic and face- , The coupling between them ensures that the alloy is a stable austenitic steel.
