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.

镍基高温合金中碳化物组分相形成过程的控制

确定了碳化物相析出热力学过程的数学依赖性，并对化学元素的结构和分布进行了实际研究。建立了合金化学成分对碳化物形态和类型影响的规律。研究表明，根据系统中引入的化学元素，碳化物的类型及其化学成分会发生变化，从而减少材料中裂纹形成的过程。建立的多组分体系Ni-22.5Cr-19Co-1.9Al-3.7Ti-2W-1.4Ta-1Nb-0.15C的依赖性使得从合金的化学成分确定碳化物的化学成分成为可能。对计算方法得到的结果和实验数据进行了评价，结果分析具有良好的收敛性，可推荐工业应用。

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.
