Outline of Final Research Achievements

Method for improving room temperature formability of magnesium alloy sheets by controlling generation of deformation-twin were examined. It is known that a large amount of twins were generated in Mg-Ca alloys during rolling, and “bending and tension deformation” is known to be an effective process for introduction of twin generation in Mg alloys. Thus, in this study, effects of bending and tension deformation on the texture formation and room temperature formability of Mg-Ca alloys were investigated. As a result, it was revealed that the texture of Mg-Ca alloys can be controlled by the bending and tension deformation, and its room temperature formability was improved by the texture control.

Academic Significance and Societal Importance of the Research Achievements

マグネシウム合金の有する強み(軽量性)を活かした輸送機器用構造部材を実用化するためには、大型・高寸法精度部材の大量生産が必要不可欠となる。そのためには、室温成形性の向上は必須かつ最適な手段である。本研究では、マグネシウム合金の双晶形成を制御し、それに基づいた材料設計により室温成形性を飛躍的に改善することを目的としている。本技術が実現すれば、マグネシウムが元来有する強みと相まって、社会的に高い波及効果を期待することができる。
