Abstract
Abstract
The time-dependent behaviour of AlSi4Mg2 alloy has been investigated with the ICF model. It shows that the apparent viscosity increases with decreasing the shearing time and increasing the resting time, especially at the initial stage. The above variations depend on its microstructure affected by solid volume fraction and shear rate, respectively. It is found that the agglomerating time is about 100 times as long as the deagglomerating time, which agrees with the experiment data.
