摘要
Recrystallized commercial purity aluminum samples were deformed to true strains of 0.095 and 0.262 by uniaxial tension. Microtexture data were analyzed to quantify orientation gradients between the grain interior and the grain boundary of nearest neighbor crystallites. The gradients were characterized in terms of the length over which a significant gradient was observed and the maximum misorientation. Estimated length ratios were observed to obey an inverse power law relationship with Taylor factor(s). (C) 2009 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
