Aluminium-based particulate metal-matrix composites (PMMC's) are candidate materials for both aerospace and automotive applications. Their near-isotropic properties allow them to be processed through conventional thermomechanical routes. However, the microstructural response of these materials to such processes, whether at room or elevated temperatures, has not been widely studied. One aspect which has received little attention is the recrystallized grain size following cold work and subsequent annealing as a function of common processing parameters such as strain, annealing temperature and heating rate to annealing temperature. This paper presents data on the recrystallized grain size of a PMMC consisting of a 2xxx series alloy matrix reinforced with alumina particles as a function of strain, annealing temperature and heating rate. This behavior is compared with the unreinforced aluminium matrix subjected to the same treatments.
