GRAIN AND GRAIN BOUNDARY STRUCTURE EVOLUTION WITHOUT TEXTURE CHANGES DURING NORMAL GRAIN GROWTH IN 2-D AL STRIPS

Abstract

Changes of the grain boundary character distribution and texture during normal grain growth have been investigated using the SAC-SEM based method and a 4 circle X-ray texture goniometer on A1 strips with columnar structure. The microstructure of the strips consists of regions with oriented (clusters) and randomly oriented grains. All changes of microstructure are outside the clusters during normal grain growth and consequently no texture change was observed.
