Metal-molding system and process for making foamed alloy

Disclosed is: (i) a metal molding system, (ii) a metal molding system including a combining chamber, (iii) a metal molding system including a first injection-type extruder and a second injection-type extruder, (iv) a metal molding system including a first injection-type extruder being co-operable with a second injection-type extruder, (v) a mold of a metal molding system, and (vi) a method of a metal molding system.

Metal molding system

A injection-molding process injects a semi-solid slurry with a solids content ranging from approximately 60% to 85% into a mold at a velocity sufficient to completely fill the mold. The slurry is injected under laminar or turbulent flow conditions and produces a molded article that has a low internal porosity.

Process for injection molding semi-solid alloys

An injection-molding process for molding a metal alloy into a near net shape article that is characterized in that the processing temperature of the alloy at injection is approaching the liquidus, preferably having a maximum solids content of %, whereby a net-shape molded article can be produced that has a homogeneous, fine equi-axed structure without directional dendrites, and a minimum of entrapped porosity. Advantageously, the resulting solid article has optimal mechanical properties without the expected porosity and solidification shrinkage attributed to castings made from super-heated melts.

Near liquidus injection molding process

An injection-molding process for molding a metal alloy into a near net shape article that is characterized in that the processing temperature of the alloy at injection is approaching the liquidus, preferably having a maximum solids content of 5%, whereby a net-shape molded article can be produced that has a homogeneous, fine equi-axed structure without directional dendrites, and a minimum of entrapped porosity. Advantageously, the resulting solid article has optimal mechanical properties without the expected porosity and solidification shrinkage attributed to castings made from super-heated melts. Also disclosed is a metal-matrix composite including a metallic component, and also including a reinforcement component embedded in the metallic component, the metallic component and the reinforcement component molded, at a near-liquidus temperature of the metallic component, by a molding machine.
