Recently, semi-solid forming has been mainly utilized for automotive components such as the brake cylider. Semi-solid forming is a metal processing technique, which is becoming of large interest owing to many inherent advantages from a view point of saving energy, comparing with conventional forging (solid state) and casting (liquid state). In spite of the feasibility of semi-solid forming, its industrial application is limited. The faster forming speed tends to be required with complicating the figuration of compacts to attain the stable formability. It is noted that the applied uniaxial strain rate to materials is 10^2〜10^3 s^<-1> during forming. Very few data are, however, available concerning with the compressive behavior of semi-solid materials at a commercial forming rate. A classical Split Hopkinson Pressure Bar was used to estimate the dynamic mechanical properties of semi-solid aluminum alloy.
