摘要：

The effect of a 20 vol% alumina microsphere particulate on the age-hardening characteristics of a 6061 Al matrix composite was investigated - based on microhardness, electrical resistivity and X-ray mapping - and the composite is compared to the unreinforced 6061 Al alloy. It is shown that this ceramic reinforcement can affect the age-hardening behaviour of the matrix alloy by significantly accelerating the kinetics of precipitation. This acceleration is related to a decrease in nucleation time and to an increase in the precipitate-growth rate. The relative amounts of age-hardened precipitates are also observed to be affected by reinforcement addition.
