摘要
The rheological behavior of partially solidified Al-10% Cu alloy is in-vestigated.It is found that the slurry presents the character of a psoudoplastie fluid inisothermally holding and the apparent viscosity increases with increasing cooling ratein continuously cooling.The effect of cooling rate on the apparent viscosity decreasesin high stirring rate range.The measured value of apparent viscosity is influenced bythe diameter of the screw propeller.
