Austenite in Nanostructured Maraging Steel

详细

Abstract—The structural formation and properties of austenite in martensite aged (maraging) 03N18K9M5T steel were analyzed. The morphological features of austenite, determining its resilience to heating, supercooling, and plastic deformation, were established. The difference between the characteristics of residual and reverted austenite was substantiated. The contributions of phase hardening and dispersion of crystals to the yield strength of residual austenite were determined. The role of both types of austenite in the formation of steel was shown as well.
