A method for producing a metal film from an over 50% nickel alloy melts more than one ton of the alloy in a furnace, followed by VOD or VLF system treatment, then pouring off to form a pre-product, followed by re-melting by VAR and/or ESU. The pre-product is annealed 1-300 hours between 800 and 1350 C. under air or protection gas, then hot-formed between 1300 and 600 C., such that the pre-product then has 1-100 mm thickness after the forming and is not recrystallized, recovered, and/or (dynamically) recrystallized having a grain size below 300 m. The pre-product is pickled, then cold-formed to produce a film having 10-600 m end thickness and a deformation ratio greater than 90%. The film is cut into 5-300 mm strips annealed 1 second to 5 hours under protection gas between 600 and 1200 C. in a continuous furnace, then recrystallized to have a high cubic texture proportion.

A method for producing a component includes incorporating a molding compound into a tool for producing the component, where the molding compound includes an artificial resin as a matrix and a filler material embedded in the matrix. The method includes compressing the molding compound by the tool and by the compressing forming the molding compound to a green product. The method further includes providing the green product while disposed in the tool with a layer in a sub-region by incorporating a liquid material for producing the layer into the tool and applying the liquid material to the sub-region. The liquid material is a metallic material and the layer is an electromagnetic shielding on the green product.

An apparatus for countergravity casting a metallic material, comprises: a crucible for holding melted metallic material; a casting chamber for containing a mold; a fill tube capable of extending into the crucible to communicate melted metallic material to the casting chamber; a gas source coupled a headspace of the melting vessel to allow the gas source to pressurize said headspace to establish a pressure differential to force the melted metallic material upwardly through said fill tube into said mold; and means for gettering sulfur.

Disclosed is a gear including a resettable metallic glass. The gear of the present disclosure includes, as a base material, a resettable metallic glass, wherein the resettable metallic glass includes at least one metal element selected from each of (a) the group consisting of Ti, Zr, and Hf and (b) the group consisting of Fe, Co, Ni, Cu, and Zn, and further includes at least one metal element to maximize the complexity in the thermodynamic enthalpy of mixing among constituent elements, thereby including multiple resetting cores in various atomic-scale cluster forms in an amorphous matrix, leading to a structure with maximized structural complexity.

A method for forming a mold for casting a titanium-containing article, the method including combining calcium aluminate with a liquid to produce an initial slurry of calcium aluminate and adding oxide particles into the initial slurry to create a final slurry. The method further includes introducing the final slurry into a mold cavity that contains a fugitive pattern and allowing the final slurry to cure in the mold cavity to form a mold of a titanium-containing article.

Disclosed is a continuous rapid solidification apparatus, which has a cooling roll configured to cool a molten metal supplied to an outer circumference surface thereof; a crucible configured to supply the cooling roll with the molten metal; a molten metal supply configured to melt a raw material metal and supply the crucible with the molten metal; a first chamber configured to form a sealed space where the molten metal supplied from the crucible is cooled by the cooling roll; and a second chamber configured to be formed of a space separated from the first chamber and to form a sealed space where the molten metal is supplied to the crucible by the molten metal supply.

A vacuum smelting device with mold-temperature control design includes: a chamber body and a cabin door, wherein the chamber body and the cabin door form a vacuum closed space; a smelting crucible disposed in the vacuum closed space for smelting raw materials to a molten metal; a casting mold also disposed in the vacuum closed space for accommodating the molten metal poured from the smelting crucible, and solidifying the molten metal to an as-cast alloy; and a mold-temperature control module surrounding the casting mold for controlling the temperature of the casting mold.

A die casting system includes a die including at least one die component that defines a die cavity, a spar received within a portion of said die cavity, a shot tube in fluid communication with the die cavity, and a shot tube plunger moveable within the shot tube to communicate a molten metal into the die cavity to cast a hybrid component. The spar establishes an internal structure of the hybrid component, and one of the internal structures and an outer structure of said hybrid component is an equiaxed structure.

A casting method includes: forming a seed, the seed having a first end and a second end, the forming including bending a seed precursor; placing the seed second end in contact or spaced facing relation with a chill plate; contacting the first end with molten material; and cooling and solidifying the molten material so that a crystalline structure of the seed propagates into the solidifying material. The forming further included reducing a thickness of the seed proximate the first end relative to a thickness of the seed proximate the second end.

A device for casting electrode grids for producing lead acid batteries in a continuous casting process. The device includes a casting wheel and a casting shoe which rests on an outer circumference of the casting wheel. Liquid lead exiting the casting shoe flows into a concave mold of the casting wheel surface and is removable as a solidified lead strip. The casting shoe is made up of two or more zones, at least a first hot zone with a temperature above the melting point of lead and a second, thermally separated zone with a temperature below the melting point of lead. Cooling the lead strip from two sides (the wheel side and the shoe side) avoids columnar crystal formation and increases the casting speed to 40 meter per minute and above. Thermal isolation of the lead feeding tube avoids re-flowing of lead to a lead pot, reducing PbO formation.
