Titanium Alloys for High Temperature Applications — a Review

Abstract

The development of energy efficient gas turbine engines with high thrust-to-weight ratios has increased the need for more titanium static and rotating engine components because of the high property-to-density ratio of these alloys. In the last 20 years advances in alloy development and microstructure control have made commercially available a family of high temperature titanium alloys which can operate at temperatures as high as 590°C (1100°F). The relationships between high temperature properties and alloy chemistry, processing, resulting microstructures and protective coatings will be discussed, and applications of these alloys in aerospace systems will be highlighted. © 1984 by Freund Publishing House Ltd.
