摘要：Magnesium matrix composites reinforced with TiC particulates was successful synthesized by in-situ synthesis method. The dislocation arrangements in the composites have been investigated. Compared to magnesium alloy, there is high dislocation density in the composites. Besides dislocation network, dislocation pile-ups have been found in a-Mg and ?-Mg17Al12 phases. They are confined in the slip planes, and some of them pile up against the grain boundaries. The dislocation arrangements in the composites are due to the addition of TiC particulates. Moreover, the compound twin reveal in the casting composites, which is beneficial to the deformation behavior of the composites. ? Published under licence by IOP Publishing Ltd.
