1·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.
与传统的等温淬火工艺相比，“两步法”组织得到显著细化，而基体组织中残余奥氏体体积分数及含碳量无明显不同。
2·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。
3·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.
白口铸铁按基体分为铁素体白口铸铁、铁素体-奥氏体白口铸铁、奥氏体白口铸铁、珠光体白口铸铁和马氏体白口铸铁。
4·It is shown that the erosive resistance at high angle of impact is wrose than at low angle regardless of austenite or martensite matrix;
结果认为无论马氏体基体还是奥氏体基体，高角度冲击下的耐磨性都低于低角度冲击；
