Abstract Titanium alloys are the principal replacements, and in many cases also prime candidate materials to replace (i) aerospace special and advanced steels, owing to their higher specific strength properties, (ii) aluminium alloys, due to their better elevated temperature properties and (iii) nickel-base superalloys for high pressure compressors of modern engines, owing to their superior intermediate temperature (up to 600 °C) creep strength and excellent oxidation and corrosion resistance and good damage tolerant properties. This chapter summarily presents the chemical compositions, properties, aerospace applications and briefly covers (a) the physical metallurgy of titanium alloys, (b) Primary (Melting and Casting) and Secondary (Processing) processes and (c) alloy development (commercially pure Ti, α, near-α, α + β and β alloys). Towards the end, the Indian scenario is presented in terms of available production facilities and some of the indigenous alloys.
