奥氏体晶粒度显示方法的试验探索

Experimental Exploration on the Discovery Method of Austenite Grain Size

晶粒度是金属材料的重要显微组织参量,本文简要介绍了三种显示奥氏体晶粒度的方法,主要介绍了汉钢计量检验中心实验室采用氧化法试验的过程。

Grain size is an important microstructural parameter of metal materials. Three methods of displaying Austenite grain size are briefly introduced in measurement and inspection center. The process of oxidation test in the laboratory is mainly introduced.
