Etched in this way, the grain structure shows up much more clearly and image analysis could be used. Once an alloy steel part is heat treated, only etching can be used to try to reveal the prior-austenite grain boundaries, that is, the austenite boundaries present when ASTM and Grain Size Measurements - MetallographyIn heat-treated steels, it is recognized that the grain size of the product of the heat treatment, usually martensite, is not measured or cannot be measured. For low-carbon steel, the martensite forms in packets within the parent austenite grains. In high-carbon martensites, we do not observe any convenient structural shape that can be measured.
