Abstract:The history and current situation of the high-temperature Ti-based alloys were reviewed, with the emphases on the cases of the United States, Great Britain and Russia. The development trends of those alloys were discussed . In the light of the difficulties met in the development and design of those alloys, several ways have been proposed to solve those problems, i.e. selecting new alloying elements, using additives of rare earth elements, designing Ti3A- and TiAl-based creep resistant alloys and developing oxidation-resistant coatings.
Key words: high-temperature Ti-based alloys hot strength thermal stability alloying elements titanium aluminides high-temperature coatings
