Abstract
Metal-matrix composites with discontinuous reinforcement are attractive for high-temperature applications because of their creep strength. An additional benefit is the ease of fabrication through a number of processing routes. The magnitude of creep strengthening depends on the chemistry, size, and volume fraction of the reinforcement phase. By using a dislocation-creep-mechanism map, it is possible to predict the level of creep strengthening in discontinuously reinforced aluminum-matrix composites.
