<p>PCT No. PCT/AU84/00123 Sec. 371 Date Feb. 27, 1985 Sec. 102(e) Date Feb. 27, 1985 PCT Filed Jun. 19, 1984 PCT Pub. No. WO85/00308 PCT Pub. Date Jan. 31, 1985.A method of forming a composite article having a first and a second metal components, and a resultant composite metal article, wherein a flux coating is applied over at least a substantially oxide-free bond surface of the first component, the first component with said flux coating is preheated and, with said first component positioned in a mould to fill a portion of a cavity of the mould, a melt for providing the second component is poured into the mould so as to flow over said bond surface; the first component being preheated to a first temperature and the melt being poured at a second temperature such that, on flowing over the bond surface, the melt displaces said flux coating and wets said bond surface, and that such initial temperature equilibration between said surface and the melt results in an interface temperature therebetween at least equal to the liquidus temperature of the melt, thereby resulting on solidification of the melt in attainment of a bond between the components.</p> |
