中文摘要：

有不同作文的一系列奥氏体的生铁样品被扔，在样品的镍的部分被锰为经济理智代替。Erosioncorrosion 测试在 2wt% 下面被进行硫磺的酸和 15wt% 石英沙。在镍的部分被锰代替以后，结果证明生铁的矩阵仍然是奥氏体。(Fe， Cr )₃ C 是在生铁的一个普通阶段，并且镍是在高镍的生铁的主要 alloying 元素；而，(Fe， Mn )₃ C 在低镍的生铁与增加的锰内容被观察。在 erosioncorrosion 测试下面，生铁的重量损失率与增加时间增加。穿戏一个更重要的角色比在决定重量损失的腐蚀。为有高、低的镍内容的生铁的重量损失的过程是不同的，这被显示。包含 7.29wt% 镍和 6.94wt% 锰的生铁的侵蚀抵抗等价于包含 13.29wt% 镍的生铁的。

英文摘要：

A series of austenitic cast iron samples with different compositions were cast and a part of nickel in the samples was replaced by manganese for economic reason. Erosion–corrosion tests were conducted under 2wt% sulfuric acid and 15wt% quartz sand. The results show that the matrix of cast irons remains austenite after a portion of nickel is replaced with manganese.（Fe,Cr）3C is a common phase in the cast irons, and nickel is the main alloying element in high-nickel cast iron; whereas,（Fe,Mn）3C is observed with the increased manganese content in low-nickel cast iron. Under erosion–corrosion tests, the weight-loss rates of the cast irons increase with increasing time. Wear plays a more important role than corrosion in determining the weight loss. It is indicated that the processes of weight loss for the cast irons with high and low nickel contents are different. The erosion resistance of the cast iron containing 7.29wt% nickel and 6.94wt% manganese is equivalent to that of the cast iron containing 13.29wt% nickel.
