The tensile tests on the silicon carbide whisker and paniculate reinforced 2124A1 and 2024Al alloy composites fabricated by P/ M technique were carried out at the temperatures ranging from room temperature to - 196C . and the fracture surfaces were examined. The cryogenic strength of the composites increases with the decreasing test temperature. Clean interface is beneficial to the improvement in cryogenic strength of the composites. The effect of the interface characteristics on the paniculate composite is less than that on the whisker composite. With the decreasing temperature, the increase in strength of the whisker composite is more than that of the paniculate composite, which could be attributed to different strengthening mechanism.
