Abstract: The bar material of GH4049 containing W inclusion was made for different aero parts such as blade and so on.In order to avoid the parts containing of W inclusion being used in aero-engine, this paper proposed an X-ray inspection method for finished or semi-finished products, and through analysis and test, the feasibility of X-ray inspection to high temperature alloy containing W inclusion was proved. X-ray inspection technology of high temperature parts containing W inclusion was established.
