GH4049合金钨夹杂射线检测工艺研究

The Research of Radiographic Testing Technology for High Temperature Alloy GH4049

含钨夹杂的GH4049棒料被加工成叶片等不同的航空零部件。为避免带有钨夹杂的零部件装机使用,提出了采用射线检测方法对涉及的在制品和成品进行检查。通过分析研究和试验,证明了射线检测高温合金钨夹杂的可行性,确立了高温合金钨夹杂零部件的射线检测工艺。

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.
