<p>A weldable titanium alloy particularly intended for use at high temperatures and under conditions of high stress in aircraft engines, the alloy having the composition 5.6% aluminium, 4%tin, 4% zirconium, 1 %niobium, 0.25% molybdenum, 0.5% silicon, 0.05% carbon, optionally containing 0.2 % tungsten and being used in the heat treated condition. The heat treatment would normally comprise a solution treatment above the beta transus, typically at 1080°C, and an ageing or stress reliefing treatment at a temperature of approximately 650°C for approxi- matey 24 hours.</p> |
