Abstract
The development of high-temperature titanium alloys has contributed significantly to the spectacular progress in thrust-to-weight ratio of the aero gas turbines. This paper presents anoverview on the development of high-temperature titanium alloys used in aero engines and potential futuristic materials based on titanium aluminides and composites. The role of alloy
chemistry, processing, and microstructure, in determining the mechanical properties of titanium alloys is discussed. While phase equilibria and microstructural stability consideration have
restricted the use of conventional titanium alloys up to about 600 "C, alloys based on TiPl (or,), E,AINb (0), TiAl (y), and titaniumltitanium aluminides-based composites offer a possibility of
quantum jump in the temperature capability of titanium alloys.
