Abstract

Five methods for characterizing second-phase particle pinning potential in twin roll cast AA 3105 have been evaluated experimentally and analytically. A stereological expression, S_V/4, has been demonstrated as a robust means for characterizing the degree of particle pinning in real material systems with neither the assumption of particle shape nor size distribution and without the experimental difficulty of unfolding the size distribution.
