Numerical simulation study on vacuum gravity precision casting of titanium alloy impeller and experimental validation

Aiming at the problems of many internal defects and low molding quality of cast titanium alloy impeller blades, By designed two casting systems, the finite element method is used to numerically simulate the gating system.. The design optimization of casting system was studied during the casting and...
