Application and development of titanium alloy and titanium matrix composites in aerospace field

Abstract

In recent years, China has continuously strengthened the construction and development of the aerospace industry. While strengthening air military power and accelerating the pace of exploring the space field, the demand for titanium alloys and titanium-based composites with high strength, low density and high temperature resistance has increased. In order to explore the performance of titanium alloys and titanium-based composites in different service environments, this paper reviews the application and development status of titanium alloys and titanium-based composites in aerospace. Through the study of the high-temperature titanium alloys, high-strength titanium alloys, flame-retardant titanium alloys, low-temperature titanium alloy and titanium-based composites, the application and research overview of high-performance titanium alloys and titanium-based composites are described, the problems in the current research are discussed. It is pointed out that the composition control, structural design, and process coupling for titanium alloys and titanium-based composites used for aerospace are the future research directions.
