摘要： A method is disclosed for heating a cold worked sheet of superplastically formable metal composition to recrystallize its microstructure to a suitably formable condition and further to heat the sheet to a temperature for an immediate forming operation. The method utilizes a combination of hot air convection heating and infrared radiation to rapidly accomplish the heating. High temperature infrared heating elements provide most of the energy during an initial high heating rate phase and then those elements are shut off and heating is completed with controlled temperature hot air to prevent overheating of the sheet metal.

摘要： Present invention concerns a method for making fine-grained, formable aluminium alloy strips containing (by weight) essentially between 0.5-6.5% Mg, 0-0.50% Si, 0-0.60% Fe, 0-1.2% Mn, 0-0.50% Cr, by twin-roll casting to a thickness ranging between 4 and 6.5 mm and cold rolling the strips to an intermediate gauge and reroll annealing the intermediate gauge material. The reroll-annealed material is then cold rolled to a final sheet gauge followed by a final recrystallizing or back annealing. The combination of controlled casting parameters, controlled amounts of Fe, Si, Mn, Cr and Mg and reroll and final annealing temperatures results in an improved sheet product in terms of finer grain size, higher elongation and formability, age softening and better corrosion resistance. Homogenization may be performed at 420null C. to 550null C. for a period of 4 to 15 hours and recrystallization is performed at 280null C. to 375null C. for a period of not less than 4 hours and not more than 8 hours.

摘要： High strength aluminum alloy powders, extrusions, and forgings are provided in which the aluminum alloys exhibit high strength at atmospheric temperatures and maintain high strength and ductility at extremely low temperatures. The alloy is produced by blending about 89 atomic % to 99 atomic % aluminum, 1 atomic % to 11 atomic % of a secondary metal selected from the group consisting of magnesium, lithium, silicon, titanium, zirconium, and combinations thereof, and up to about 10 atomic % of a tertiary metal selected from the group consisting of Be, Ca, Sr, Ba, Ra, Sc, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Y, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, W, and combinations thereof. The alloy is produced by nanostructure material synthesis, such as cryomilling, in the absence of refractory dispersoids. The synthesized alloy is then canned, degassed, consolidated, extruded, and optionally forged into a solid metallic component. Grain size within the alloy is less than 0.5 nullm, and alloys with grain size less than 0.1 nullm may be produced.

摘要： A magnesium, manganese and copper-containing aluminum alloy sheet material suitable for use in high elongation forming processes is produced according to an improved thermomechanical process. The sheet material is produced by continuous casting with an as-cast gage of 5 to 35 millimeters and immediately hot rolling with a final strip exit temperature between 200null C. and 350null C. and then coiling. The hot rolled coil is annealed at 450-560null C. to homogenize the microstructure. After cooling to ambient temperature, the coil is cold rolled to desired sheet thickness with a net gage reduction of 50-90%. After suitable recrystallization of the cold worked microstructure the sheet is ready for hot, high elongation forming.

摘要： The present invention concerns procedures for producing an alloy from a eutectic alloy system, in order to form a workpiece for rolling or extrusion purposes by, for example, producing an Al—Mg—Si alloy, which can be precipitation-hardened, which alloy, after having been heated to a temperature above the solubility temperature of phases which can be precipitated, is kept at this temperature until the phases have dissolved and is cooled at a cooling rate which is rapid enough to avoid most of the precipitation of the phases and slow enough to avoid most of the precipitation of dispersoid particles. At cooling rates within this interval, most coarse phases which have a reductive effect on the processing rate can be avoided and, at the same time, the number of small dispersoid particles which have a reductive effect on the mechanical properties after hardening is limited.

摘要： This invention provides a fluidized-bed furnace, in which the work piece is heat-treated in a fluidized bed formed by filling a vessel with particles and blowing hot air into the vessel to fluidize the particles. It includes a cantilevered dispersion tube disposed in the fluidized bed, and provided with air outlets directed downward, from which the hot air is blown out. This invention also provides a heat-treatment apparatus incorporating a rotary heat-treatment furnace, in which a work piece is heat-treated while being rotated in the fluidized bed, as the solution and/or aging treatment furnaces; removing dust from the exhaust gases discharged from the solution treatment furnace by a dust collector, and recovering the waste heat from the exhaust gases by an heat exchanger as the heat source for the aging treatment furnace; and also incorporating an automatic carrier which charges or discharges the work piece into or out of each furnace. The fluidized-bed furnace is improved to require a lower investment cost and smaller space and prevent thermal energy loss more efficiently than the conventional one, and suitable for a heat treatment furnace for metals, e.g., Al alloy.
