Abstract

Official abstract text for this publication.

An aluminum-based composite material includes an aluminum parent phase, and stick-shaped or needle-shaped dispersive matter of aluminum carbide dispersed in the aluminum parent phase. A method of manufacturing the aluminum-based composite material includes a step of mixing aluminum powder having a purity of 99% by mass or higher with a stick-shaped or needle-shaped carbon material, and pressing and molding a resulting mixture, so as to prepare a compacted powder body. The manufacturing method further includes a step of heating the compacted powder body at 600C to 660C to react the carbon material with aluminum in the aluminum powder, so as to disperse the stick-shaped or needle-shaped dispersive matter of aluminum carbide in the aluminum parent phase.

First claim

Opening claim text (preview).

What is claimed is: 1. An aluminum-based composite material comprising: an aluminum parent phase; and stick-shaped or needle-shaped dispersive matter of aluminum carbide dispersed in the aluminum parent phase, wherein the dispersive matter dispersed in the aluminum parent phase is set to have a ratio of a length to a diameter in a range of 1 to 30, the length being in a range of 0.01 nm to 1000 nm, the diameter being in a range of 0.01 nm to 200 nm so as to maintain electrical conductivity, wherein the dispersive matter is formed such that a stick-shaped or needle-shaped carbon material is reacted with aluminum in the aluminum parent phase by sintering to achieve the dispersion of the dispersive matter, wherein an amount of the dispersive matter is in a range of 0.1% to 2.0% by mass of carbon content, and wherein the carbon material consists of at least one kind selected from the group consisting of carbon nanotubes, carbon nanohorns, and carbon nanofibers. 2. An electric conductor comprising: the aluminum-based composite material according to claim 1 .
