摘要
选用20Cr Mn Ti进行氧化法制备奥氏体晶粒度,并尝试用饱和苦味酸水溶液+洗洁精作为浸蚀液代替15%盐酸酒精溶液,结果表明:采用饱和苦味酸作为浸蚀液能更简单、清晰地显示奥氏体晶粒度且容易掌握。
20CrMnTi is selected to prepared austenite grain size through the oxidation style, and an etching solution saturated picric acid ＋ detergent is tried to use instead of 15% hydrochloric acid alcohol solution. The results show that using saturated picric acid as an etchant can be more simply and clearly show austenite grain size and easy to learn.
