摘要： A method of forming a wrought material having a refined grain structure is provided. The method comprises providing a metal alloy material having a depressed solidus temperature and a low temperature eutectic phase transformation. The metal alloy material is molded and rapidly solidified to form a fine grain precursor that has fine grains surrounded by a eutectic phase with fine dendritic arm spacing. The fine grain precursor is plastic deformed at a high strain rate to cause recrystallization without substantial shear banding to form a fine grain structural wrought form. The wrought form is then thermally treated to precipitate the eutectic phase into nanometer sized dispersoids within the fine grains and grain boundaries and to define a thermally treated fine grain structure wrought form having grains finer than the fine grains and the fine dendritic arm spacing of the fine grain precursor.

摘要： An apparatus for molding a metal material. The apparatus includes a vessel with portions defining a passageway through the vessel. An inlet is located toward one end and a member or agitation means is located within the passageway. A plurality of heaters are located a length of the vessel. The first of the heaters is located immediately downstream of the inlet and is a low frequency induction coil heater whereby the temperature gradient through the vessel's sidewall is minimized.

摘要： A vessel for processing feed stock material into molten or semi-molten state. The vessel includes a body defining an interior surface, an inlet, for receiving the feed stock material and an outlet discharging the material. The sidewall of the body comprises three layers, referred to as the shell, an intermediate layer and a liner. The intermediate layer is disposed between the shell and the liner and is formed of material softer than the materials forming the shell and the liner. The presence of the intermediate layer minimizes the thermal gradient along the thickness of the barrel.

摘要： An apparatus for processing materials which are highly corrosive while in a thixotropic state, for example aluminum. The apparatus includes a barrel which is adapted to receive the material through an inlet. In the barrel, the material is heated and subjected to shearing, forming a highly corrosive, semi-solid slurry which is discharged from the barrel through a nozzle. The barrel is constructed with an outer layer of a first material and an inner layer of an Nb-based alloy which is bonded to the outer layer. Positioned within the passageway of the barrel is a screw, the rotation of which operates to subject the material to shearing and move the material through the barrel. The screw is constructed with an outer layer of the Nb-based alloy that is molecularly bonded to an inner core of a different material. The Nb-based alloy is resistant to the corrosive effects of the material being processed.
