Abstract

There are several characteristics of casting components with large scales: large shape size, complex structures, large wall thickness variations, many locations of varying sections and large portion of thin-wall area. In the process of casting, shrinkage cavity, shrinkage porosity, inclusion, cold separation, and other casting defects are easy to form, which seriously reduce the quality of castings and even lead to the waste of castings, limiting the development of high-performance aero-engine. The key to the development of large scale aero-engine castings contains the detection technology of casting defects, the quantitative prediction of casting defects, and the control and repair technologies of casting defects in large castings.
