ALUMINUM-MAGNESIUM-SCANDIUM ALLOYS WITH HAFNIUM

摘要

Al-Mg-Sc based alloys include hafnium to prevent degradation of tensile properties during rolling and other thermomechanical and high temperature operations. The alloys are comprised of aluminum and 1.0-8.0 % Mg, 0.05-0.6 % Sc, and 0.05-0,20 % Hf. Other elements, including Mn and Zr, may be added to the alloys to enhance their tensile properties further.
