ABSTRACT:
A composite article having a first and a second metal component, 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 the flux coating is preheated and, with the first component positioned in a mold to fill a portion of a cavity of the mold, a melt for providing the second component is poured into the mold so as to flow over the 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 the flux coating and wets the bond surface, and that such initial temperature equilibration between the 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.
