Although Al-based hybrid composites are promising materials to produce structural components,
their mechanical behavior under extreme aging conditions has not been studied much. In this article, the
effects of aging heat treatments at different temperatures and aging times on the mechanical behavior of
2024 aluminum alloy (Al2024) and Al2024/graphene/b4c hybrid nanocomposite synthesized by
mechanical alloying (MA) and powder metallurgy are discussed. T3 heat treatment was applied to all
samples. The mechanical behavior of the samples was determined by the hardness and tensile test
measurements as a function of the aging time. After 12 hours of aging period, the samples showed
mechanical stability in hardness and tensile strength performances. With increasing aging time, a great
increase in the mechanical properties of the samples was observed. In addition, the mechanical properties
of the samples reached the maximum level at the aging temperature at 190C and decreased with increasing
temperature. Therefore, the optimum aging heat treatment performance was obtained in aging time of 12
hours and aging temperature of 190 C.
