Abstract

Structure, phase’s content, hardness, microhardness of structure components in hightemperature strong nickel-chromium alloy are studied. Cr7C3, TiC carbides and Ni3Al intermetallic compound are exposure with the help of X-ray structure analysis. It was shown that research alloy is characterized of structure homogeneity in a broad temperature interval. This alloy has structure and properties stability of details for metallurgical equipment working at the high temperatures.

Keywords: STRUCTURE, PHASE’S CONTENT, HIGH-TEMPERATURE STRONG, NICKEL-CHROMIUM ALLOY, CARBIDE, INTERMETALLIC COMPOUND
