SUMMARY
Retained austenite is formed during the cooling of steel, particularly in specific temperature ranges outlined by the iron-carbon TTT diagram. The mechanism for its retention involves the stability of austenite at certain cooling rates, which prevents its transformation into martensite or other phases. Understanding the structural arguments for retained austenite formation is crucial for metallurgists and materials scientists aiming to optimize steel properties.
