(英) Application of Al-Mg-Si alloys to automotive body panels is increasing to reduce the weight of automobiles. As for Al-Mg-Si alloys, the improvement of mechanical properties has been attempted by small amount of additive element. Recently, it is pointed out that the iron additive causes the adverse effect on bending property. Mechanical properties with additive elements of chromium and iron in the Al-Mg-Si alloy was investigated using tensile test. Appearance of hydrogen embrittlement was also determined at three strain rates using hydrogen micro-print method. (日) Al-Mg-Si合金にクロムおよび鉄を添加した合金の機械的特性を引張試験によって検討した．また，水素マイクロプリント法を用いて，水素脆化の発生の有無を三つの歪み速度で調べた．
