摘要：

The flow stress of a 1060 Al/Al2O3 composite increases rapidly with strain rate due to the higher dislocation accumulation rate and the increasing strength of dislocation barriers. The Al/Al2O3 interfaces were found to be well bonded even after high-rate deformation of the composite. MgAl2O4 particles observed at Al/Al2O3 interfaces in the composite of the present study are thought to improve the interface strength. Unlike in pure aluminium, a well-developed cell structure was not observed in the deformed 1060 Al/Al2O3 composite. The absence of a well-developed cell structure is thought to result from a more homogeneous slip distribution in the composite.
