NOVELTY - Busbar comprises an aluminum (Al) metal matrix composite (MMC) comprising 0.01-2 wt.% nanoscale carbon particles, where the nanoscale carbon particles are evenly distributed throughout an entirety of the AI-MMC. USE - The busbar is useful in electrical power distribution application which is an automotive application (all claimed), and outdoor electrical applications. ADVANTAGE - The busbar: has an electrical conductivity of greater than 50% international annealed copper standard (IACS), an ultimate tensile strength (UTS) of greater than 80 MPa, and an elongation of greater than 10%; has an electrical conductivity of greater than 50% IACS, a UTS of greater than 120 MPa, and an elongation of greater than 30%; has an electrical conductivity of greater than 50% IACS, a UTS of greater than 200 MPa, and an elongation of greater than 1%; has an electrical conductivity of greater than 50% IACS, a UTS of greater than 300 MPa, and an elongation of greater than 3%; has UTS of at least 90% of its UTS prior to heating, after heating either at 400 degrees C for 1 hour or at 310 degrees C for 400 hours; shows a total displacement of less than 5%, after creep testing for 100 hours at 150 degrees C with an applied load of 80% of its room-temperature yield strength; shows a total displacement of less than 5%, after creep testing for 500 hours at 150 degrees C with an applied load of 80% of its room-temperature yield strength; has a total carbon content of up to 0.5 wt.% and an even distribution of carbon, in which the total area fraction of carbon particles of larger than 1 mu m of less than 0.38%; reduces weight and cost; and offers a significant amount of strengthening and creep resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for achieving even distribution of nanoscale carbon particles throughout an entirety of MMC component, comprising obtaining MMC feedstock material comprising a metal matrix and nanoscale carbon particles and processing the MMC feedstock material through a solid-state deformation process to form the MMC component with even distribution of the nanoscale carbon particles throughout an entirety of the MMC component.
