Controlling deformation and flow of semisolid alloy slurry is the key of die casting of semisolid alloy.

The deformation and flow of metal in the process of roll forging are much different from those of ordinary die forging, So are the design of its technology, preliminary forming dies and dressing dies.

Grid-experiments are performed to investigate metal flow and deformation in the shear-extrusion process of tubular components with branches.
