THE IMPACT OF CHEMICAL COMPOSITION ON MECHANICAL PROPERTIES OF THE ALLOYED STEEL

Abstract

Based on mathematical and physicochemical modeling a studied the effect of alloying elements (chromium, molybdenum, vanadium) in the formation of the mechanical properties of steel. The intervals of the content of alloying elements that ensure the fulfillment of the required norms are determined. Dependences of the change in the mechanical properties of doped rolled steel from the index of the structural state d are constructed.
