Role of deformation mechanisms and grain growth in microstructure evolution during recrystallization of Mg-Nd based alloys
2019
Abstrakt
The microstructure and texture evolution during static recrystallization of Mg-Nd alloys were investigated. Depending on the third alloying element added into Mg-Nd alloy, either Al or Zn, diverse textures are formed during recrystallization annealing.
The rolled Mg-2Nd-1Zn sheet shows a high activity of prismatic slip and the formation of a weak texture with basal pole spread in the sheet transverse direction. In contrast, a strong texture with a basal pole spread in the rolling direction was formed in the Mg-2Nd-1Al sheet.
An equivalent growth of the recrystallized grains at the early annealing stage retains their orientations during grain growth. (C) 2019 Acta Materialia Inc. Published by Elsevier Ltd.
