METHOD FOR THERMAL PROCESSING OF ARTICLES CONSISTING OF ALLOYS ON THE BASIS OF IRON (VARIANTS)

摘要

The invention relates to the field of thermal processing of articles consisting of steel and alloys on the basis of iron with a carbon content of up to 4.3% by mass. In order to reduce the duration of the technological processes used for producing articles consisting of alloys on the basis of iron with a set structural state, the first variant of the method comprises heating the articles so as to form austenite and then cooling, which is performed under conditions which ensure the formation, in the structure of the alloy, of regions of austenite with a chemical composition similar to eutectoid with the subsequent formation in said regions of marinite and a set structural state so as to produce perlite with a different degree of dispersion and/or hardened structures. The second variant of the method comprises heating the article, which is performed under conditions which ensure the formation, in the structure of the alloy, of marinite and then cooling with the formation of a set structural state so as to produce perlite with a different degree of dispersion and/or hardened structures. When implementing the methods, pulsed cooling, plastic deformation and the action of a magnetic field are used.
