Research Progress of Effect of Porosity on the Fatigue Behavior in the Cast Alloy

In this article,the effect of porosity defects on the fatigue performance of cast alloy is reviewed.Related research indicates that porosity defect have a remarkable impact on the fatigue crack initiation,the fatigue crack growth and other aspects of whole fatigue process.The fatigue properties of cast alloy factors such as pore size,shape volume fraction,location distribution,etc.
