对含锰永模等温球墨铸铁进行了实验室磨损和侵蚀试验，合金含量为1%、2%和3%。研究和讨论了Mn的加入对合金耐磨性能和拉伸性能的影响。结果表明，随着Mn含量从1%增加到2%，磨损和侵蚀体积损失呈减小趋势；Mn添加量进一步增加到3%导致磨损损失增加。拉伸强度和伸长率性能也是如此。根据石墨的结构特征对这些数据进行了解释。
Laboratory abrasion and erosion tests have been reported on permanent moulded austempered ductile iron with manganese as alloying element at three levels, i.e., 1%, 2% and 3%. The influences of Mn addition on the wear and tensile properties have been studied and discussed. The results indicate that with increase in Mn content from 1% to 2%, the abrasion and erosion volume losses are exhibiting decreasing trend. Further increase in Mn addition to 3% has resulted in an increase in wear losses. Same is the case with the tensile strength and percentage elongation properties. These data have been interpreted based on the structural features including graphite morphology.
