Development of quantitative research in titanium alloys

Because of excellent comprehensive properties, titanium alloys draw wide attentions from researchers and users. The key research direction is the relationship among composition, processing, microstructure and properties. The design of composition and the relationship among processing, microstructure and property were qualitativly analyzed in the past, and good results were achieved. In recent years, the quantitative relationships among composition, processing, microstructure and properties were studied, and some results were achieved. This paper interviews the development of quantitative design of composition for high strength titanium alloy and the research of quantitative relationship among processing, microstructure and property, mainly including the quantitative design method of composition for high strength titanium alloy, quantitative characterization for microstructure, quantitative relationship between microstructure and properties and quantitative relationship between processing and properties, and the quantitative relationships, were tested and verified.
