Growth Rate of Small Fatigue Cracks of Cast Magnesium Alloy at Different Conditions
Some differences between the growth behaviors of small fatigue crack of cast AM50 magnesium alloy at different elevated temperature and at open and closed states were investigated based on in-situ observations with scanning electron microscope (SEM). These results indicate that the growth rates of small fatigue cracks depend on not only the stress levels but also the elevated temperature and crack states. The fatigue crack growth rates were estimated based on novel and conventional methods.
