Abstract
The fabrication of a 99.999% aluminium conductor reinforced by a powder metallurgy (P/M) processed Al-Fe-Ce alloy is described. Long continuous lengths of composite conductors consisting of 1, 4, and 19 Al filaments have been produced by streamline die hot extrusion and cold working by conventional wire drawing or cold hydrostatic extrusion. Microstructural observations and some limited electrical resistivity and mechanical property data are presented along with an analysis of the contamination of high-purity Al conductors by diffusion during annealing
