Abstract
The effect of stress on a corrosion mode of a thixomolded magnesium alloy in a NaCl aqueous solution was studied with elucidating the time dependent characteristics of corrosion products and an actual concentrated stress value in α-Mg and Mg17A112 phases around an artificial notch. The corrosion mode was quite different depending on the sign of the stresses; a fine and dense amorphous hydro-oxide formed in the region of tensile stress whereas a coarse amorphous oxide formed in that of compressive stress. The concentrated tensile stress at the notch root relaxed within two minutes by the corrosion followed by gradual relaxation to zero.
