PARTICLE STIMULATED NUCLEATION AND THE FORMATION OF RSCRYSTALLIZATION TEXTURE IN Al-Mn ALLOY CONTAINING PARTICLES Ⅱ. Interaction Between Particles and Other Nucleation Sites and the Formation of Recrystallization Texture

本文在分析了Al—Mn合金形变时不同形变取向基体中粒子周围亚晶转动规律及对应的粒子促进形核晶粒的取向特征的基础上，进一步测定了处在晶界，立方带上的粒子周围新晶粒的取向分布，最后分析了再结晶织构的形成．结果表明，处在这些位置上的粒子周围新晶粒一方面保留了晶内PSN晶粒的取向特征。

On the basis of analyzing the subgrain rotations around paricles within deformed matrices and their nucleation, a further investigation of the orientations of grains formed at particles locating at grain boundaries and cube bands was carried out and the formation of recrystallization texture was analyzed. Results reveal that the orientations of the grains at these places retain the orientational features of particle stimulated nucleation within deformed matrices and possess the characteristics of nucleation at grain boundaries or at cube bands. Recrystallization texture is produced by nucleation at different sites.
