L. Salvo et al., AGE-HARDENING BEHAVIOR OF LIQUID-PROCESSED 6061-ALLOY REINFORCED WITHPARTICULATES AND SHORT FIBERS, Composites. Part A, Applied science and manufacturing, 27(12), 1996, pp. 1201-1210
The age hardening of 6061-based metal matrix composites containing var
ious types of reinforcement and produced by both rheocasting and prefo
rm infiltration has been investigated. It is shown that there is no re
al effect of the processing route on age hardening of these materials
whatever the ageing temperature. Reinforcement size effects have also
been investigated for particulate reinforcements and it is shown that,
for particulates larger than 3 mu m, mechanical effects dominate over
those due to microstructure. Copyright (C) 1996 Elsevier Science Limi
