Effect of Viscosity Measurement Method to Simulate High Pressure Die Casting of Thin-Wall AlSi10MnMg Alloy Castings

In the present study, a rotating cylinder viscometer (RCV) was adopted to measure the viscosity of AlSi10MnMg aluminum alloy. The results show that the measured viscosity is much higher than previously reported viscosity of aluminum alloys measured by oscillation vessel viscometer. The viscosity measured by RCV was introduced into the simulation of the filling progress of high pressure die casting (HPDC) for thin-walled castings of aluminum alloy (TWCA). The simulated results match well with the experimental results indicating that the RCV is the most appropriate to use for simulations of HPDC for TWCA.
