1. A composite material comprising an aluminum-based matrix, comprising:
an aluminum-based matrix comprising a plurality of grains, wherein each of the grains has a plurality of sub-grains; and a self-organized phase present at a sub-grain boundary between the plurality of sub-grains, wherein the self-organized phase has a band structure and comprises a solid solution of aluminum and a non-metal element, wherein a deviation in lattice constant between the self-organized phase and the sub-grains is in a range of 1% to 5%, wherein a first sub-grain is provided on one side of the self-organized phase and a second sub-grain is provided on the other side of the self-organized phase, and a crystal orientation direction of the second sub-grain is tilted at an angle of 10 degree to 10 degree with respect to a crystal orientation direction of the first sub-grain.
