准确测定残留奥氏体量是金属材料研究关心的问题之一。目前通用的方法是以B.L.Averbarch和M.Cohen的单线对直接对比法为基础的。此法的优点在于简单易行,不足的是在许多情况下测算结果波动较大。造成波动的原因是多方面的。
Accurate determination of residual austenite is one of the issues of concern in the study of metallic materials. The current common method is based on the one-line direct comparison method of B.L.Averbarch and M. Cohen. The advantage of this method is that it is easy to operate, and the downside is that in many cases, the measurement result fluctuates greatly. The reasons for the volatility are many.
