[3] Effect of aging time under applied stress on precipitation microstructure and strengthening of stress-aged Al-Mg-Si Alloys

*Takumi HARA1, Shinji MURAISHI2 (1. Tokyo Institute of Technology (Graduate student), 2. Tokyo Institute of Technology (Associate Professor))

Keywords:アルミニウム合金、Al-Mg-Si合金、時効析出、応力時効

応力時効によるAl-Mg-Si合金の析出バリアント間の析出密度の差は明瞭に確認されていない. そこで, 応力時効中の応力負荷時間を変化させ, 応力時効が析出物の核生成と成長, 変形強度の異方性に与える影響を調査した.
