Definitions
- This alloy provides a good compromise between high strength, cost, oxidation/corrosion resistance and resistance to TCP formation.
- a gas turbine engine comprises the turbine disc made from the nickel-based alloy composition of the present invention.
- a constant is added to convert the elemental additions of niobium (8.57 g/cm 3 ) and tantalum (16.4 g/cm 3 ) to an "aluminium equivalent", thus, niobium and tantalum have correctional factors (determined from their density relative to aluminium) of 0.3 and 0.15 respectively. From Figures 7-11 a relationship between elemental additions (based upon titanium, aluminium and niobium) and target alloy strength was derived.
- a minimum tungsten content of 0.7 wt.% is required at cobalt of 9.6 wt.%, this amount of cobalt not falling under the scope of the invention, to achieve the minimum creep merit index of 2.4 x 10 -15 m -2 s, Figure 20 .
- molybdenum is limited to 4.1% for improved alloy stability (see below), thus a tungsten content of greater than 1.9 wt.% is preferred as this results in a better balance of creep resistance and alloy stability.
