Abstract
The first metallographic studies of D.K. Chernov, the Russian metallurgist, metal scientist, are considered to be the beginning of the scientific study on the structure of cast metal. Dmitry K. Chernov in meticulous detail studied the process of crystal formation and growth within the solidification of liquid metal, gave a diagram of the structural zones of steel ingots, and developed the theory of successive crystallization, comprehensively studied the defects of cast steel [1], and outlined the results of his research and the necessity of studying the internal quality of cast metal in the historical message "Studies related to the structure of cast ingots" addressed to the Imperial Russian Technical Society on December 2, 1878. The modern technical literature on metallurgical science contains a lot of different scientific studies in the field of the quality of continuously cast steel billets and the evolution of cast metal during hot rolling. There are domestic and foreign books and textbooks, as well as numerous collections of conference proceedings and papers containing studies on the structural and chemical heterogeneity of continuously cast carbon steel. This paper presents comprehensive information about the influence of metallurgical heredity on the structure and mechanical properties of hypoeutectoid steel during subsequent hot rolling. The presented data show the development of macroscopic, metallographic, and instrumental methods for studying the chemical and structural heterogeneity of continuously cast steel. Classical and modern research methods are compared.
Keywords
