ALUMINUM-BASED COMPOSITE MATERIAL AND MANUFACTURING METHOD THEREFOR

摘要

An aluminum-based composition material comprises an aluminum parent phase (1) and a dispersoid (2) obtained from rod-shaped or needle-shaped aluminum carbide that is dispersed in the aluminum parent phase. A method for manufacturing an aluminum-based composite material comprises a step for manufacturing a green compact by mixing an aluminum powder of at least 99 mass% purity with a rod-shaped or needle-shaped carbon material and compacting. Said manufacturing method also comprises a step for reacting the carbon material with the aluminum in the aluminum powder by heating the green compact at a temperature of 600-660°C to disperse the dispersoid made of rod-shaped or needle-shaped aluminum carbide in the aluminum parent phase.
