Investigation of the effect of different total concentration and ratio of Si and Mn content on the dendritic structure and segregation inhomogeneity of cast carbon steel and its transformation after hot plastic deformation. \u0000Methods of research. To determine the effect of the content of Si and Mn, experimental ingots with a variable chemical composition within the grade were made for three steel grades used for the manufacture of railway axles – grade OS according to DSTU 31334, F according to AAR M 101 and EA1N according to EN 13261. To determine the dendritic structure microstructural analysis was used after etching in sodium picrate. \u0000Results. A comparative analysis of the microstructure of the experimental heats of steels with a variable chemical composition has been carried out. The ratio of content in steel Si and Mn in the cast state and after deformation is established. A significant effect of the total deoxidation in steel on the formation of microhardness inhomogeneity over the cross section of a carbon steel ingot and microinhomogeneity of the structure of individual sections is shown. It was found that after deformation, the central zones turned out to be the most worked out (especially for steel with a chemical composition within the EA1N grade, characterized by an increased content of Mn). \u0000Scientific novelty. The study of the influence of fluctuations in the content of the basic elements of carbon steel leads to the development of ideas about the formation of a dendritic structure and segregation heterogeneity in railway axle steels. \u0000Рractical value. Knowledge of the principles of segregation formation is necessary to determine further modes of deformation and heat treatment not only for continuously cast billets or ingots, but also for final products.","PeriodicalId":423067,"journal":{"name":"Innovative Materials and Technologies in Metallurgy and Mechanical Engineering","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129905400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several metal strips of steel 09Г2С arranged crosswisely have been welded for making of a specimen. The specimen of steel 09Г2С with weld longitudinal arrangement and rectangular cross-section has been produced of the received detail by milling with cooling.

To study and analyze in a comparative order the influence of factors of the controlled pulse process of electrode wire supply on some basic mechanical characteristics of seams and welded rollers in the processes of welding and surfacing of nickel-containing steels. \u0000Methods of research. The study the mechanical characteristics of seams and welded rollers was carried out using modern laboratory equipment and appropriate techniques. This made it possible to determine how the pulse feed parameters affect the strength characteristics of the weld and near the weld zone over the entire cross-sectional area of the weld or weld layer. Detailed characteristics of feed pulses were determined using a welding process analyzer to obtain oscillograms of power parameters of arc combustion with their analysis, including determining the stability of the arc process for different types of pulses.

Due to the fact that the strength characteristics of the weld are among the most important, attention is paid to their definition and analysis. The strength characteristics depend on many parameters, in particular the thermal characteristics of the process, the structure of the weld metal, the presence of non-metallic inclusions and so on. All these factors were studied with the help of appropriate instruments, and on the basis of numerous comparative photos of microstructures on sections of the cross section.
