<p>Titanium alloys having improved strength/ductility/fracture toughness combinations over prior art alloys and comprising 11.5-12.5 % vanadium, 1.1-1.7 % iron, 3.5-4.2 % aluminium, proportions being by weight. The alloys according to the invention are preferably heat treated to maximise fracture toughness and fatigue strength in a heat treatment regime which comprises the steps of annealing at 790-810°C, water quenching over a period of 1-6 hours and ageing in a salt bath at 500-530°C over a period of 6-10 hours.</p> |
