Corrosion Fatigue of AM50 and AE44 Alloys at Various Temperature and R-Ratio

Reported in this paper are the experimental results obtained from corrosion fatigue tests of high pressure die cast (HPDC) AM50 and AE44 magnesium specimens immersed in NaCl and GM9540P solutions at various temperature, low and high R-ratio. Test specimens were loaded under cyclic loading at temperature of −5°, 25°, and 80°C. It is shown that fatigue life was reduced significantly in these corrosive environments. Although the fatigue life (in …
