[5] The high strength and light weight could reduce the number of towers needed per kilometer for long distance transmission lines.
Al-Ca composite conductor was invented by Russell and Anderson at Ames Laboratory of the U.S. Department of Energy with the goal of developing the next generation power transmission cables.
[7] Al/Ca composite is produced by powder metallurgy and severe deformation processing (extrusion, swaging, wire drawing).
[8] The formation of intermetallic compounds at the interface would stabilize the microstructure to avoid the degradation of its various properties during exposure to elevated temperatures,[9] such as those encountered during emergency overload situations.
Newest development An Al/Ca (20 vol%) nanofilamentary metal-metal composite was produced by powder metallurgy and severe plastic deformation.
