Paper Title:
In Situ SEM-EBSP Observations of Recrystallization Texture Formation in Al-3mass%Mg Alloy
  Abstract

This study presents in situ observations of recrystallization texture formation in Al-3mass%Mg using SEM concurrent with electron back scattering pattern (EBSP) with hot stage. In the present discussion, the emphasis is on the characteristics of the preferred growth or the shrinkage of Cube and other oriented grains. The in-situ observations of recrystallization demonstrate clearly that the nucleation, growth and shrinkage of recrystallized grains occur simultaneously in each orientation in each region. The overall development of recrystallization texture depends on the balance of nucleation/growth and shrinkage/disappearance of each orientation during recrystallization. The preferential growth is determined by the grain boundary mobility between recrystallized grains or the clusters composed of several similar oriented grains, i.e. Cube clusters or S clusters, and neighboring deformed matrix, and the competitive growth with the surrounding grains. On the other hand, the isolated oriented grain and the strain-stored grains tend to shrink and disappear during recrystallization and grain growth.
