Among high-temperature structural materials, due to the excellent performance, titanium aluminum alloy is regarded as a highly potential candidate for stationary and rotating parts of new type high thrust ratio aeroengine and aerospace propulsion systems. In order to thoroughly understand the global research status of titanium aluminum alloy, this article is written based on the research literature data of titanium aluminum alloy in the CNKI database and Web of Science database, with the help of CiteSapce software to make a visual knowledge map, combining both the quantitative analysis and qualitative analysis. The methods of this study objectively reveal the status of both domestic and foreign researches on titanium aluminum alloy. The contents of this study include the research institutions, authors, keywords, as well as the highly cited documents of different literatures. The results show that the research institutions are mainly universities and scientific research institutes. Large ratio of studies are performed with the cooperation between foreign research institutions, while Chinese research institutions-cooperation study only take small ratio. Frequency and influence of Chinese authors-literature citations are relatively high. The research mainly focus on microstructure, mechanical properties, etc. There is a large number of high cited references in the research of titanium aluminum alloy in Chinese and foreign languages from 2010 to 2016.
