The dynamic mechanical responses of three aluminum matrix composites reinforced with in-situ Al2O3 and TiB2 particulates were investigated in compression at strain rates ranging from 1.7×10-3 s-1 to 1.5×103 s-1. The results showed that these composites exhibit a high strain-rate sensitivity. The strength and initial strain hardening rate of the composites tended to increase with increasing strain rate. And increasing the particulate content led to an increase in the strain-rate sensitivity of composites. Furthermore, composites containing Al3Ti plates exhibited the highest strain-rate sensitivity. © 1999 Elsevier Science B.V. All rights reserved.
