On the example of maraging ZI90-VI steel (03Kh12N8K5M2TYu) influence of heat in intercritical temperature interval on phase composition and properties under drawing of cold-deformed wire is studied. delay in two-phase ((A+Γ) area leads to the formation of significant amount of stabilized austenite. Such effect can be connected with local Γ-solid solution enrichment by alloying elements. The treatment in between limiting temperatures gives strength of the wire compared to routine treatment (quenching) as well as quite high ductility after 45% deformation.
