Complex alloy, a nickel base resistant to corrosion and oxidation.

摘要

P complex alloy based on nickel and containing iron, which also contains (in percentages by weight) 0,5 to 4% of boron, 0,05 to 1,5% of carbon and 0,5 to 5% of silicon. With respect to the known alloys of the same type, the iron content of this alloy was increased from 5 to 30% by weight, and there is added a quantity of 0,1 to 20% by weight of at least one element forming carbide and / or a boride, such as mo, v, nb, w, zr, hf, ta, ti, cr (the latter element not being used alone). This alloy does not give rise to the formation of february or fe3 c, or else it forms only a very small amount of these two compounds, and it makes it possible to obtain a ductility, which can be qualified as good at a very good. / p & & p & this alloy is greater, the economic point of view, to the conventional alloys of the same type, by virtue of the iron content higher than that of these alloys in which it is desired, on the contrary, to maintain the iron content to a level as low as possible in addition, it has a resistance to oxidation and corrosion better than that of these alloys. / p
