Abstract
The dynamic similarity of two geometrically similar extrusion processes was examined. The flow lines, values of the flow function ψ, and velocity components were compared for the hot extrusion of SAE 1018 steel at 1800 deg F and 10 ips, and the superplastic eutectic alloy of lead–tin at room temperature and 0.088 ipm. The comparison showed a good agreement between the two cases and that dynamic similarity of the flow fields was achieved under the previous conditions. Material properties were examined and results indicated that similarity of the mechanical properties is necessary for the dynamic similarity of the flow fields.
