在较高温度时，这种材料全部是奥氏体，但随着冷却就进入到铁素体和奥氏体稳定状态的区域。

At high temperatures, the material is entirely austenite, but upon cooling enters a region where the stable phases are ferrite and austenite.

镍奥氏体球墨铸铁的基体得到强化不仅使其耐蚀性能稳定，而且综合性能也得到提高。

As the result of strengthening of the matrix of nickel austenite nodular iron, not only its corrosion resistance stability was improved, and also its overall properties were increased.

奥氏体稳定化取决于化学稳定化、尺寸稳定化和热稳定化；

The stabilization of austenite depends on the chemical stabilization, the particle sige effect and the austenite thermal stabilization.
