Abstract

The grain growth law has been verified for a range of grain sizes produced in three composites containing 6061 aluminum alloy matrix and 0.10, 0.15 and 0.20 volume fractions of alumina particles (VFAP), with particle sizes of 10, 15 and 20 μm respectively, by solutionizing at 540°C for different times. The solutionizing time affects the (a) microstructures developed at the interface between the particles and the matrices and (b) age hardening characteristics, microstructures and microhardness values, at 200°C.
