%X The rheological behavior of the semi-solid slurry of A356 aluminum alloy has been studied through a Couette-type viscometer. The experimental results show that the apparent viscosity of semi-solid A356 alloy increases with the fraction solid increasing, but decreases with the shearing rate increasing in the steady-state. When the solid fraction reaches a critical value, the apparent viscosities increase rapidly. An empirical equation that shows the effect of fraction solid and shearing rate on the apparent viscosity of semi-solid A356 alloy is built as the following, =13.61exp(6.09 ) -1.01.
