高铬铸铁残余奥氏体测定的探讨
DISCUSSION OF RETAINED AUSTENITE MEASUREMENT ON HIGH-CHROMIUM CAST IRON
摘 要
对高铬铸铁残余奥氏体测定的几种方法进行了比较。X射线衍射和磁性法都有其自身的局限性和适用范围。对有择优取向的组织来说，用旋转摆动的X射线可较准确地测出残余奥氏体的数值。

Abstract
Some methods of retained austenite measurement on high chromium cast iron were compared. The X-ray diffraction and magnetic permeability methods have their limits and suitable scope. For the structure of perfered orientation,the volume of retained austenite could be measured correctly by rotating and tilting specimen holder.
