摘要：

The static and dynamic behaviour of two metal-matrix (Al-Cu 2124 and Al-Li 8090) composite materials, reinforced by particulate SiC have been studied under torsion and tension in the temperature range 25 to 550 degrees C. All the dynamic tests are based on the SHPB technique. The tests show that the strain rate has an obvious influence on the maximum deformation and a smaller influence on the strength at fracture for the two materials. For temperatures lower than 250 degrees C, the strength and the ductility remain almost constant. They decrease at high temperature (>250 degrees C). The effects of strain rate and temperature on the behaviour is same for both tension and torsion.
