Computer-aided Engineering (CAE) could predict the possible defects in the solidification progress of titanium alloys during centrifugal casting. This paper describes the simulation method, which is applied to simulate the centrifugal casting progress of titanium alloys. This method includes: filling and solidification simulation,temperature field simulation during solidifieation and predictions of shrinkage porosity. This method is implemented in InteCAST and has been applied to simulate and analyze the casting progress of a typical complex titanium plate casting. The application shows that the software is able to accurately predict pore, shrinkage porosity and other defects that may arise in titanium castings.
