Definitions
- the subject of the invention is a nickel alloy.
- These parts are constituted of blades fitted into platforms, the assembly of which on an engine constitutes a ring. Certain of these parts are traditionally constructed from a nickel alloy known as René 125, but which is particularly liable to produce cracks on moulding, during the solidification of the molten metal, which can constitute an important cause of rejects.
- the alloy proposed here comprises, in a nickel base, from 9.5% to 9.90% by weight of cobalt, 8.70% to 9.00% by weight of chromium, 6.65% to 7.05% by weight of tungsten, 3.67% to 3.87% by weight of tantalum, 1.77% to 1.97% by weight of molybdenum, 0.10% to 0.12% by weight of carbon; and it is differs from the conventional composition of René 125 by levels of 4.80% to 5.00% by weight of aluminium, 1.48% to 1.52% by weight of hafnium, 2.28% to 2.33% by weight of titanium, 0.0005% to 0.01% by weight of boron.
- the alloy does not in principle comprise other ingredients, except at much lower levels than those mentioned until now, or only present as impurities. It is thus underlined in particular that zirconium, quite abundant in René 125, is eliminated entirely or almost entirely from the present alloy (at the most 0.007% by weight), as are phosphorous and sulphur (at the most 0.001% each by weight). Certain other criteria, corresponding to secondary aspects of the invention, can still advantageously be respected as will be detailed hereafter.
- This alloy resists the hot formation of cracks much better than René 125; it may thus be employed in processes of foundry manufacturing parts of complex shapes.
- Titanium and hafnium their effect was the same but less important, such that their total elimination is not recommended, a slight reduction in the level sufficing to reduce enormously the probabilities of cracks.
- the levels proposed in the invention led to probabilities of cracks at least four times less than in René 125 (the comparative tests each time related to a single variant element).
- Total level of hafnium, titanium and aluminium the reject rate had a low levelling off between around 8.73% and 8.77% (total of levels), then increased sharply, then being multiplied by at least around four. Aluminium does not have in itself the harmful role of the other elements mentioned above and its level is even increased in the invention, but this criterion shows that it cannot be in excess. The total level is advantageously below the latter figure.
- Nickel the reject percentage of parts due to cracks dropped from a level of 59.71% of nickel, and reached a levelling off corresponding to very low reject rates from around 59.83%.
- the level is advantageously above the latter figure.
- Silicon it is at the most 0.10% by weight in René 125, and advantageously present as traces in the invention.
- the heat treatment used for the tests as for the manufacture by moulding of the bladed distributors was a T3R, namely a heating to 1175° Celsius for 30 minutes, then a cooling to 1095° Celsius in 6 to 10 minutes, then a cooling in the oven to 650° Celsius, then a cooling in air, and an annealing at 815° Celsius for 16 hours under vacuum or protective atmosphere.
