The two-stage extrusion method, by means of which the metals can be easily extruded against high hydrostatic pressure, is developed. The effects of pressure on the extrusion ability of several brittle metals and the mechanical properties of the extruded metals are examined. It is found that the extrusion ability of magnesium and aluminum alloy AC2C-F increases with back pressure. The results are explained through slip line theory. The effect of back pressure on the mechanical properties of the extruded metals is significant for brittle metal such as magnesium, and is little for ductile metal such as the aluminum alloy 5052.
