Abstract The apparent viscosity and rheological behavior of nanoSiC P /Al-5Cu composites were studied by using a high temperature coaxial rotating cylinder viscometer. The results show that mass fraction of nanoSiC P is an important factor for apparent viscosity of the nanoSiC P /Al-5Cu composites and there is a great enhancement of apparent viscosity of the slurry with the increase of
