A tensile test was carried out on the two kinds of SiC fiber-reinforced Al alloy composite wires, SiC/pure-Al and SiC/Al-5.7 % Ni, which were quenched or annealed. The effect of the matrix hardness and microstructural change on the tensile strength and its scatter has been investigated. The results showed that the SiC/Al-5.7 % Ni composite wires maintained a higher strength than the SiC/pure-Al composite wires after the wires were quenched from a temperature up to 450℃, and it had less strength than SiC/pure-Al after being heated to a temperature over 550℃. The scatter of the strength of SiC/Al-5.7 % Ni wire increased as quenching temperature increased, but the strength of SiC/pure-Al wire had no change in scatter. The results above were explained by the matrix microstructure, and by the tensile strength of the extracted fibers.
