摘要
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 Mn 1s NEXAFS spectrum of the alloy Fe Mn Al Cr has been detected by synchrotron radiation X ray at BEPC National Laboratory.The multiple scattering cluster(MSC)theory analyses show that the Mn and Fe atoms in the alloy exist as bcc and fcc microcrystals respectively.The coupling between them makes the alloy to be a stable austenite steel.
