Effect of temperature on the fatigue cracking mechanisms in A356 Al alloy

This work builds on our previous investigation of the room temperature fatigue cracking mechanisms of an A356 Al alloy [1]. Here, we analyze the elevated temperature fatigue cracking mechanisms in cast and friction stir processed (FSP) A356, and contrast them with the room temperature behavior. Two...
