一种显示T12钢奥氏体晶粒与内部组织的腐蚀方法

Corrosion Method to Show the Austenite Grain and Internal Microstructure of T12 Steel

介绍了采用10%硝酸酒精和3%双氧水对退火T12钢进行腐蚀和清洗的操作方法,并与常用的4%硝酸酒精腐蚀的结果进行对比分析。结果表明,用10%硝酸酒精和3%双氧水进行腐蚀和清洗更易于清晰显示和分辨T12钢的奥氏体晶粒与内部细微组织形貌。

The new method of corrosion and cleaning of annealed T12 steel with 10% nitric acid alcohol and 3% hydrogen peroxide were introduced,and the results of commonly used 4% nitric acid and alcohol corrosion were compared.The results show that the corrosion and cleaning of 10% nitric acid alcohol and 3% hydrogen peroxide are easier to display and distinguish clearly the austenite grains and internal fine microstructure of T12 steel.
