Abstract

1426125 Ni base superalloy HOWMET CORP 23 Jan 1974 [6 March 1973] 03049/74 Heading C7A Ni balance are vacuum cast by adding to a substantially oxygen and sulphur free melt sufficient magnesium to provide the 0.001-0.02%Mg content of the solidified alloy and casting and solidifying the magnesium containing melt. The magnesium may be added to the melt contained in a vacuum induction furnace in the form of a Ni-15%Mg master alloy and the melt which may comprise scrap from previous castings may be cast within 15 minutes to 2 hours after the magnesium addition into chilled metal moulds to provide ingots suitable for remelting. The substantially oxygen and sulphur free melt may be obtained by the use of components free of impurities and by the deoxidizing and desulphurizing effects of zinconium and boron.
