摘要：

Twin-roll cast (TRC) AZ31 alloy (Mg-3 wt.% Al-1 wt.% Zn) was subjected to annealing heat treatment at 420 C which resulted in an important change in the original strong basal texture. It was observed that the unique TRC structure, which is a combination of both cast and deformed structures, is responsible for this texture alteration upon annealing. The change in crystallographic orientation is attributed to the particle-stimulated nucleation of new grains with random orientations. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd.
