Abstract Scope |
Recycling of aluminum alloys is the best practice to reduce the carbon footprint of automotive aluminum products, however the aluminum scrap, “twitch”, is contaminated with impurity elements and the cost of recycling techniques is significantly high. In parallel, the U.S. electricity delivery system undergoes changes to improve its reliability and resilience to extreme weather conditions. The design of a novel thermostable aluminum-based conductor for overhead transmission lines utilizing high volumes of aluminum twitch is a promising solution and a cost competitive way to recyclability. In the present study, CALPHAD-based ICME tools are employed for the design of an aluminum cable conductor with high strength, high electrical conductivity, and high thermostability via melt-spinning and high temperature aging. A hierarchical system-based approach is adopted, and the thermodynamic calculations are aided by DFT databases to design novel intermetallic compounds supporting new classes of aluminum alloys compatible with recycling of automotive scrap. |
