本文研究了Fe-7%Al-2%C中残余奥氏体和马氏体电子衍射图中“多余”斑点的来源。目前的解释不同于以前的研究人员。得出的结论是，高密度的细碳化物沉淀物的直径50微米负责额外的反射。淬火过程中析出物具有钙钛矿结构，并在奥氏体中外延生长。当马氏体在较低温度下形成时，析出物在原位转变。
The origin of “extra” spots in electron diffraction patterns taken from retained austenite and martensite in Fe-7 pct Al-2 pct C has been investigated. The present interpretation differs from that of previous investigators. It is concluded that a high density of fine carbide precipitates 50Å in diameter is responsible for the extra reflections. The precipitates have the perovskite structure and grow epitaxially in the austenite during quenching. When martensite forms at a lower temperature, the precipitates are transformedin situ.
