Molding of Aluminum Foams by Using Hot Powder Extrusion
In order to form aluminum foams directly from powder, a combined process of hot powder extrusion and molding is proposed.Aluminum powder mixed with a foaming agent is extruded into the mold through the die heated to a temperature higher than the melting point, and the mold is filled with the aluminum foam.When a stainless steel pipe is used for a s
