SEM In Situ Study on Fatigue Crack Growth of LC9 Aluminum Alloy Subjected to Elevated Temperature

Abstract:

Experimental investigations of fatigue cracking behavior of LC9 aluminum alloy (AA LC9) subjected to elevated temperature were conducted with scanning electron microscope (SEM). Results indicate elevated temperature is important for the fatigue crack growth of AA LC9. Based on small crack growth, crack growth rate for AA LC9 is characterized.
