Abstract Scope Existing varieties of overhead high-voltage transmission cable lack versatility for increased specific strength and electrical conductivity, for both AC and DC transmission. Al/Ca deformation formed metal-matrix composite (DMMC) conductors have the potential to reach higher specific strengths and electrical conductivity than widely used aluminum conductor steel reinforced cable and are superior for DC power transmission. A PM route for Al/Ca DMMCs will be described that employs powder blending, die pressing, canning of compacts, warm extrusion, and drawn wire at different levels of deformation strain for testing. The simplistic synthesis, abundance of elemental components, and superior bulk material properties indicate Al/Ca DMMCs will be cost-competitive with industry-leading cable with an increased operational life. Mechanical and microstructural analysis of thermal aging results up to 1000h at 160-200C informed the selection of an upper operating temperature limit promoted by improved Ca-filament intermetallic reinforcement. Work funded by USDOE-OE through Ames Lab contract DE-AC02-07CH11358.
