A process for producing a molded material that can form metallic glass material in a state of lower viscosity, and can manufacture a small structure of several 10 μm or less in a comparatively short time while precisely controlling shape thereof, by the process comprising a heating step of heating supercooled state metallic glass material or a solid metallic glass material at a temperature increase rate of 0.5 K/s to a temperature at or higher than a temperature at which a crystallization process for a supercooled liquid of the metallic glass material begins, and a molding step of transfer molding the metallic glass material until the crystallization process for the supercooled liquid of the metallic glass material has been completed. In addition, the purpose is also to provide the molded material that has been formed by this process, a wavefront control element, and a diffraction grating.

Disclosed are high-strength aluminum alloys and methods of making and processing such alloys. More particularly, disclosed are aluminum alloys exhibiting improved mechanical strength. The processing method includes homogenizing, hot rolling, solutionizing, and multiple-step quenching. In some cases, the processing steps can further include annealing and/or cold rolling.

A method for forming a structure using an interim temper process is provided. A metal material is partially-aged to a stable temper that does not require cold storage. The partially-aging step is completed at a supplier facility prior to the metal material being received by the manufacturer. Once received by the manufacturer, the partially-aged metal material is heated to a first temperature to perform retrogression. A structure is formed from the partially-aged metal material after performing the retrogression. The structure is shaped and inspected. The structure is then heated to a second temperature in an age oven to reach its final aged state. The final aged state may be close to, meet, or exceed a T6 temper.

A copper alloy that does not contain beryllium and has a 0.2% offset yield strength of at least 80 ksi and an electrical conductivity of at least 48% IACS is disclosed. The copper alloy contains nickel, silicon, chromium, manganese, zirconium, and balance copper. The alloy is prepared by cold working, solution annealing, and aging. The alloy can be used for example, as a heat sink.

A structure is heated in a tool. The structure is quenched in the tool such that a shape of the structure is maintained, in which quenching is performed by contacting the structure with a quenching medium.

Methods and heat-treated cast aluminum alloy components for a vehicle formed from an aluminum alloy having high levels of recycled aluminum scrap are provided. The alloy may have, by mass, silicon at 5% to 11%, magnesium at 0.5%, iron at 0.2% to 1.1%, copper at 0.5%, zinc at 0.5%, titanium at 0.2%, chromium at 0.02%, manganese at 0.05%, strontium at 200 ppm; an alloying element at 50 ppm to 500 ppm selected from the group consisting of: barium, lanthanum, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and combinations thereof, and a balance aluminum. The heat-treated cast aluminum alloy component is substantially free of faceted iron-containing intermetallics having a platelet shape and at least one region has a yield strength of 180 MPa and an elongation of 7%.

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.

Disclosed herein is a method of forming a high strength aluminum alloy. The method comprises heating an aluminum material to a solutionizing temperature for a solutionizing time such that the magnesium and zinc are dispersed throughout the extruded aluminum material to form a solutionized aluminum material. The method includes quenching the solutionized aluminum material to form a quenched aluminum material. The method also includes aging the quenched aluminum material to form an aluminum alloy, then subjecting the aluminum alloy to an ECAE process to form a high strength aluminum alloy.

A continuous casting and rolling line for casting, rolling, and otherwise preparing metal strip can produce distributable metal strip without requiring cold rolling or the use of a solution heat treatment line. A metal strip can be continuously cast from a continuous casting device and coiled into a metal coil, optionally after being subjected to post-casting quenching. This intermediate coil can be stored until ready for hot rolling. The as-cast metal strip can undergo reheating prior to hot rolling, either during coil storage or immediately prior to hot rolling. The heated metal strip can be cooled to a rolling temperature and hot rolled through one or more roll stands. The rolled metal strip can optionally be reheated and quenched prior to coiling for delivery. This final coiled metal strip can be of the desired gauge and have the desired physical characteristics for distribution to a manufacturing facility.
