Cryogenic Treatment
Deep-freeze treatment of metals to boost hardness, wear resistance, and dimensional stability
Cryogenic treatment subjects metal components to temperatures below -150°C to transform retained austenite and improve hardness, wear resistance, and dimensional stability. Research, experiments, and prototypes; some commercial use in tooling and aerospace. Applications include cutting tools, bearings, and critical components. Research continues into mechanisms, optimal protocols, and broader material applicability.
