Abstrakt: It is established the effect of nickel content in medium carbon complex-alloyed steel on structural and phase transformation, critical points position, structure quantitative parameters and critical quenching rate. Continuouscooling transformation diagrams of overcooled austenite decomposition in steel with original composition are presented. Typical steel microstructures which are formed at cooling with different rates are described. The positive effect of nickel content on a complex of rolled plate mechanical properties after quenching and low tempering is shown. The results of the investigation can be used for the design of high-strength cold-resistant steels compositions and regimes of their thermal treatment. [ABSTRACT FROM AUTHOR]
