Summary

The results of the study by multiple regression analysis of the effect of additional alloying with cerium, vanadium, copper and boron on the start and finish temperature of the  δ → γ phase transformation, the content of ferrite and austenite in the structure of cast steel and after its quenching, the austenite grain size, the bonding energy of atoms alloying elements with the grain boundary. The quantitative laws of such influence are established.

Keywords: steel, complex doping, austenite, phase transformations, multiple regression analysis.
