Study on Porosity of Aluminum Alloy Casting Treated by Hot Isostatic Pressing
In order to eliminate porosity of aluminum alloy casting,which was not avoided effectively by foundry technique,effect of that porosity eliminated by hot isostatic pressing was tested.The results show that after the hot isostatic treatment,through X-Ray detection,the casting porosity was evidently improved;and inside quality of castings can attain demand of standard.This illustrates that eliminating porosity of the aluminum castings by hot isostatic pressing is feasible,which may provide some reference for aluminum castings eliminating porosity,too.
