摘要：

The influence of fibre reinforcement (10 vol % SiC fibres) on the precipitation and hardening behaviour of a metal matrix composite was studied using microhardness tests and transmission electron microscopy observations. It was shown that the hardening kinetics is enhanced by the SiC reinforcement due to the fact that precipitation preferentially develops on dislocation lines. Moreover, the high-temperature deformation strongly increases the precipitation rate as the material is reinforced.
