Abstract

Both creep and corrosion resistances are significant problems in the application of magnesium alloys. The synergistic effect of corrosion and stress on the viscoelasticity of magnesium alloys named corrosion creep has been studied in die-cast AZ91D (Mg-9%A1-1%Zn) and AM50 (Mg-5% A1-0.4% Mn) alloys in air and in the borate buffer solution. The highest sensitivity to creep in the corrosive environment is observed in the alloy with the highest A1 content. An electrochemical study under a tensile strain demonstrates a good correlation with corrosion creep tests.
