介绍了两种锰元素含量不同的高锰钢显微组织显示方法.采用草酸+硝酸+偏重亚硫酸钠+无水乙醇溶液作为腐蚀液,在室温下对锰元素质量分数为11%～14%的耐磨高锰钢进行腐蚀,可获得清晰完整、色彩艳丽的显微组织形貌;采用硝酸+无水乙醇溶液和盐酸+无水乙醇溶液复合的方法对锰元素质量分数为22%～28%的超低温环境用高锰钢进行腐蚀,可获得清晰的显微组织形貌.
Two methods for displaying the microstructure of high manganese steel with different manganese contents were introduced.Using oxalic acid+nitric acid+sodium metabisulfite+anhydrous ethanol solution as the corrosion solution,wear-resistant high manganese steel with a manganese content of 11%to 14%was corroded at room temperature,resulting in clear,complete and brightly colored microstructure morphology.The composite method of nitric acid+anhydrous ethanol solution and hydrochloric acid+anhydrous ethanol solution was used to corrode high manganese steel in ultra-low temperature environments with a mass fraction of manganese elements ranging from 22%to 28%,and clear microstructure morphology could be obtained.
