Abstract

The formation of Widmanstätten ferrite is not the goal of a technological process. On the contrary, it should be eliminated in order to avoid a decrease in the ductility of the steel. A detailed study of this structural component, which has no practical use, is often assumed to be unnecessary. At the same time, coarse-grain Widmanstätten ferrite makes it possible to use the range of magnification of a light microscope more efficiently for studying the mechanism of a shift γ→α transformation. The present paper is devoted to the variation of the properties and structure of Widmanstätten ferrite in the process of self-induced tempering that occurs in cooling of cast specimens of steel 20L.
