Metallurgy, Forming and Welding of Titanium Alloys

Abstract

Combination of high strength to weight ratio, good mechanical properties, corrosion resistance up to 600oC, good formability, age hardenability, ductility, creep resistance, and high corrosion resistance in marine environment, have led to a wide and diversified range of applications in defence, aerospace, welded propellant tanks, chemical plant, power generation, oil and gas extraction, jet engines, rocket parts, and other industries. Forging and processing of Ti-6Al-4V alloy elbows, tees, flanges, domes, and connections are done since 2004 at FFPL; supra-transus beta forging followed by sub-transus deformation were carried out.
