摘要：
The fatigue and mechanochemical behavior of die-cast AZ91D (Mg-9% Al-1% Zn) and AM50 (Mg-5% Al-0.4% Mn) alloys in air, transmission oil and natural mineral oil at 25 degrees C were studied. New methods were developed in this research in order to achieve better understanding of the mechanochemical effects in Mg alloys during exposure to different oil environments. It is found that the mineral oil environment causes an increase in the lifetime of both alloys in comparison with the gear oil. AM50 alloy shows excellent fatigue lifetime in oil in comparison with other environments. AZ91 shows a significantly higher sensitivity to the environment in comparison with AM50 alloy.
