Abstract—Titanium is recognized for its strategic importance as a unique lightweight, high strength alloyed structurally efficient metal for critical, high-performance aircraft, such as jet engine and airframe components. Titanium (Ti-6Al-4V) alloy is an alpha beta alloy which is solution treated at a temperature of 950 °C to attain beta phase. This beta phase is maintained by quenching and subsequent aging to increase strength. Thermal cycling process was carried out for Ti-6Al-4V specimens using forced air cooling. The compression test was conducted for various temperatures at three different strain rates. Flow behaviour of different heat treated and thermal cycled Titanium (Ti-6Al-4V) alloy were investigated.

Index Terms—Thermal cycling, Heat treatment, Solutionizing, Aging, Compressive strength.
