this work this alloy was obtained by grinding the powder constituents in mill atritor. Aiming at the in situ formation and dispersion of intermetallic aluminum carbide (Al4C3), carbon in the form of graphite with particle size less than 45 m was added in the matrix MA2024 for the use of high-energy mill eccentric.
