Description
2297095 Allo The present invention relates to alloys, and in particular
nickel-boron alloys which can be used as a master alloy.
Nickel-boron containing up to 17% boron is an important master alloy used in the manufacture of self-fluxing hardfacing and high brazing temperature nickel and cobalt base alloys.
Nickel-boron alloys are typically made by the reduction of boric acid or analogous materials in the presence of fine essentially pure nickel powder using a carbon electrode.
The resulting master alloy is made up of nickel and boron with very low levels of other elements. A typical analysis is as follows (in percentages by weight) B re Si Min 15 1.3 0.25 Max 18 2.0 0.50 c A1 0.03 0.02 0.15 0.20 Such purity is not of itself essential in the manufacture of the nickel and cobalt alloys self fluxing alloys, because the latter are themselves much more widely alloyed.
Accordingly, it is the purpose of the present invention to provide nickelboron alloys which can be made from recycled material, and therefore at lower cost, which contain further elements, which themselves contribute to the properties of the final alloy.
A nickel-boron based alloy according to the invention contains, in weight percentages, boron 12 to 20%, iron 0.2 to 2%, silicon 0.7 to 5.0%, carbon 0.1 to 3.0%, chromium 0.0 to 15.0%, cobalt 0.0 to 3.0%, molybdenum 0.0 to 3.0%, phosphorus 0.0 to 2.0%, aluminium 0.0 to 0.2% the balance being nickel, incidental ingredients and impurities. It is preferred that the alloy according to the invention contains greater than 50% by weight of nickel.
A typical analysis of such an alloy, for use as a master alloy is (in percentages by weight):
B re Si Min 12 0.2 0.7 Max 20 2.0 5.0 Another typical analysis i B Cr Fe Si 12 5.0 0.5 0.8 15.0 5.0 5.0 Another typical analysis B Cr Fe Si 12 0.0 0.2 0.8 5.0 2.0 2.0 Min Max Min Max c 0.1 2.0 c 0.1 3.0 is:
Ni Balance CO wi 0.0 3.0 Balance c MO p Ni 0.1 0.0 0.0 1.0 3.0 2.0 Balance The alloys according to the invention may contain aluminium, typically in an amount of 0.04 to 0.20% by weight.
The high boron more highly alloyed master alloys according to the invention offer the important advantage of being made from arisings of self fluxing alloys available for recycling and often at lower cost and requiring less energy than pure nickel in the process of melting the high boron containing master alloy. They also permit an easier alloying of certain elements (such as carbon particles or phosphorus) into the ultimate alloy, which can be time consuming.
