Abstract
A aluminum alloy in the form of bulk includes an aluminum matrix and carbon particles having an average particle size of 100 nm or less and dispersed in the aluminum matrix in an amount of 1 to 40 atomic % with respect to the total atoms constituting the aluminum alloy. The aluminum alloy is produced by preparing a raw material comprising aluminum and carbon as components and forming an aluminum alloy by inserting the raw material into a cavity formed by a set of dies and applying repeatedly plastic deformation to the raw material while maintaining the temperature of the raw material in the range of from 100 to 400.degree.
