Abstract
Creep in short fiber reinforced aluminum alloys is a result of three i nterconnected elementary microstructural processes: (i) loading of fib ers by dislocations; (ii) unloading of fibers by a recovery process in which dislocation loops move to the fiber ends; and (iii) fiber break age. The present work supports this view in showing that a model which is based on this microstructural scenario can successfully predict th e creep behavior of short fiber reinforced aluminum matrix composites with different fiber volume fractions. The present work also addresses the influence of the fiber aspect ratio distribution on the creep pro cess. (C) 1997 Elsevier Science S.A.
