Aluminium-based particulate metal-matrix composites (PMMC's) are being developed for application in both the aerospace and automotive industries. The near-isotropic properties of these materials allow them to be processed through the same conventional thermomechanical routes that are applied to unreinforced aluminium alloys. However, the microstructural behavior of these materials during such treatments has not been widely studied. It is also relevant to note that matrix prior to processing may strongly affect the behavior of these alloys during deformation. This paper describes the microstructural development during cold work of a PMMC consisting of a 2xxx series alloy matrix, reinforced with alumina particles, heat treated to two different starting tempers. Of particular importance is the effect of matrix temper on the integrity of the alumina particulates.
