随激光扫描速度增大，试样中的马氏体和未溶碳化物的含量不断增加，残余奥氏体含量则连续下降。

The martensitic and undissolved carbide contents continuously increase as the laser scanning speed increases while the residual austenite decreases.

锰含量提高并选取合适的淬火温度后，残余奥氏体含量及稳定性提高，抗拉强度显著提升的同时保持了较高的伸长率。

The content and stability of retained austenite is higher after more Mn is added, and also the strength is higher with preferable elongation when the appropriate quenching temperature is chose.

对有择优取向的组织来说，用旋转摆动的X射线法可准确测定高铬铸铁中残余奥氏体的含量。

For high chromium cast iron with structure of preferred orientation, its retained austenite amount can be measured accurately by X-ray method of rotating and tilting specimen holder.
