| Abstract: | With the help of ProCAST software,the filling process solidification process and shrinkage porosity formation during suction casting TiAl connecting rod for engine were simulated.The influences of some key parameters on the filling process and shrinkage porosity defect were investigated systematically,including suction hole diameter,pouring temperature and pouring velocity.The optimized processing parameters map for suction casting of TiAl connecting rod was obtained,which could be as the guide for the upcoming experimental suction casting of TiAl connecting rod.Some preventive measures were presented to overcome the possible shrinkage porosity predicted by the simulation. |
