The purpose of this study is to ascertain the material properties of metal matrix composite (MMC) that is used to reinforce pistons of automobile engines. The MMC investigated in the present study consisted of metal fibers (Fe75Cr20Si5) in an aluminum alloy matrix (AC8A). Tensile tests were performed on 100%-AC8A and MMC at temperatures of 25°C, 150°C, 250°C and 300°C. The stresses and strains of the test samples were measured ; their yield stresses, Young's moduli and tensile strengths were also determined from the experimental results.
