Abstract
The mathematical dependences of thermodynamic processes of precipitation of carbide phases are determined, and a practical study of the structure and distribution of chemical elements is carried out. Regularities were established for the effect of the chemical composition of the alloy on the morphology and type of carbides. It is shown that, depending on the introduced chemical elements in the system, the types of carbides and their chemical composition can change, which leads to a decrease in the processes of crack formation in the material. The established dependencies for the multicomponent system Ni-22.5Cr-19Co-1.9Al-3.7Ti-2W-1.4Ta-1Nb-0.15C make it possible to determine the chemical composition of carbides from the chemical composition of the alloy. The evaluation of the results obtained by the calculation method and experimental data was carried out, the analysis of the results gave good convergence and can be recommended for industrial use.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
