Compared with traditional austempered process, this new method would obtain much finer structure with nearly same volume fraction of retained austenite in matrix and carbon content of austenite.
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.
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。

According to their matrix structure, the white irons are divided into ferrite white iron, ferrite-austenite white iron, austenite white iron, pearlite white iron and martensite white iron.
