Rheological behavior of semi-solid Mg2Si/AM60magnesium matrix composites at steady state

摘要：

The microstrueture and rheological behavior of semisolid Mg2Si/AM60 magnesium matrix composite at steady state were investigated. The results show that the primary α-Mg phases are knapped by mechanical stirring and the Chinese script type reinforced Mg2Si phases exist in liquid phase and grain boundary. The analysis of apparent viscosity indicates that the apparent viscosity of semi-solid Mg2Si/AM60 magnesium matrix composite at steady state increases with increasing the volume fraction of Mg2Si and solid fraction of primary α-Mg, but decreases with increasing the shearing rate and shearing time, and the apparent viscosity keeps stable when shearing time reaches 300 s.
