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. C.
Claims18
An aluminum alloy comprising:
- an aluminum containing matrix;
- and
- carbon containing particles having an average particle size of 100 nm or less, said carbon containing particles being dispersed in said matrix in an amount of 1 to 40 atomic % with respect to the total atoms constituting the aluminum alloy, said aluminum alloy being in bulk form.
A process for producing an aluminum alloy, comprising the steps of:
- preparing a raw material comprising aluminum and carbon as components;
- and
- forming an aluminum alloy in bulk form by inserting the raw material into a cavity formed by a set of dies and repeatedly applying plastic deformation to the raw material with the set of dies while maintaining the temperature of the raw material in the range of from 100.degree. to 400.degree. C., the resulting aluminum alloy comprising an aluminum containing matrix and carbon containing particles with an average particle size of 100 nm or less dispersed in the matrix.
A product comprising an aluminum containing matrix and carbon containing particles produced by a process comprising:
- preparing a raw material comprising aluminum and carbon;
- inserting the raw material into a cavity formed by a set of dies, and repeatedly applying plastic deformation to the raw material with the set of dies, while maintaining the temperature of the raw material in the range of from 100.degree. to 400.degree. C., resulting in an alloy comprising the aluminum containing matrix and the carbon containing particles dispersed in the matrix, the particles having an average size of 100 nm or less.
