Abstract
AlLi alloys, manufactured by both ingot metallurgy (IM) and rapid solidification powder metallurgy (PM) processes, have been studied for their cavitation behavior at 450°C in the strain rate range from 2 × 10 −4 to 10 −3 s −1. The volume fraction of cavities in the IM alloy was found at all strains to be lower than that in the PM alloy. The size of cavities in the PM alloy, however, was found to be smaller than that in the IM alloy. The cavities in the PM alloy were of spherical shape, whereas in the IM alloy they were elongated. Cavity growth in both alloys was found to be dominated by a plasticity-controlled hole growth mechanism. The cavitation study has further shown that voids in both alloys pre-existed prior to superplastic deformation.
