• The present paper deals with microstructures and segregations of silicon carbide fiber reinforced copper-added aluminum and aluminum -added magnesium alloy composites, fabricated by squeeze casting, and refers to the effect of the microstructure on the tensile strength of composites. The results obtained are as follows: The results obtained are as follows: 1) Microscopic examination showed a solute element rich layer with semicircle surrounding was locally formed on fibers in the composites, whichever matrix alloy was used. The layer was identified as a eutectic constitution by EPMA decreased in thickness and area fraction, and for the case of 1% copper-aluminum matrix, no copper-rich layer was detected. 2) The appearance of the layer decreases the tensile strength of composites because of its brittleness.
