Abstrakt: Computer modeling based on thermodynamic predictions is used to show that the Ac3 temperature can vary by tens of degrees, depending on chemical composition. Chemical heterogeneity in the bulk of continuous cast steels can therefore affect the material's mechanical properties. Auger spectroscopy and mechanical tests of the hardened rolling of two general purpose steels (09G2S and St3) are used to establish that a layer-by-layer change in the yield strength in St3 steel is due to the heterogeneous composition of the solid solution. In 09G2S steel, it is due to the heterogeneity of the phase composition. [ABSTRACT FROM AUTHOR]
