Аннотация:Based on our results and the results of the experimental studies previously conducted by other researchers the analysis of the influence of remelting methods on the formation character of the KCU impact strength level and its component KCV at aging of steel 08Cr15Ni5Cu2Ti prepared by two methods of remelting are performed. The results of studying the influence of the remelting methods, thermal treatment conditions and the impurity cleanness of steels on the level of KCU and the degree of its reduction at the temperatures of strengthening aging are presented. The factors causing the difference in the structure and phase composition of the steel formed by different remelting methods are established. The temperature range in which a significant reduction in KCU occurs is determined. The hypothesis about the role of interstitial impurities in the KCU decrease at aging is suggested.
