Abstract
Creep and stress rupture tests were conducted on Albemet 162, a Be particulate reinforced Al matrix composite with a 70% volume fraction of reinforcement. A power law relationship was observed between steady state creep rate, stress rupture life, and applied stress. Considerable differences were seen between transverse and longitudinal specimens in terms of creep and rupture behaviour. Fractography of the specimens revealed that particle agglomeration of the Be phase is highly susceptible to creep damage and the primary cause of creep failure, which was observed in specimens of both orientations.
