集合組織制御による優れた室温成形性を示す マグネシウム合金圧延材の開発

Magnesium (Mg) alloys are suitable materials for weight reduction in vehicles because of their low densities and high specific strengths. However, rolled Mg alloy sheets generally exhibit a poor formability at room temperature and thus their applications are restricted. This poor formability is originated from basal slip dominated deformation as well as strong basal texture. It is known that the formability can be improved by suppression of basal texture formation. Thus, large efforts have been devoted to texture control for the purpose of enhancing the room temperature formability. In this paper, recent researches for texture control of rolled Mg alloy sheets are reviewed.0
