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，另一方面也带有晶界及立方带形核的特点再结晶织构反映了不同类型形核位置形成的新晶粒的取向特征
In this paper, based on the analysis of the rule of subgrain rotation around the particles and the orientation characteristic of the corresponding particles in promoting the nucleation of Al-Mn alloys, the particles in the grain boundaries and the cubic bands Around the new crystal orientation distribution, the final analysis of the recrystallization texture formation. The results show that the new grains around the particles at these locations retain the orientation characteristics of the intragranular PSN grains on the one hand and the grain boundaries and cubic ribbon nuclei on the other. The recrystallization texture reflects the different types Orientation characteristics of new crystal grains formed at the nucleation sites
