A method for the manufacturing of an object. The method includes receiving a desired alloy composition for the object, depositing a plurality of foils in a stack to form the object, applying heat to the stack at a first temperature to bond the plurality of foils to each other, and applying heat to the stack at a second temperature to homogenize the composition of the stack. The homogenized stack has the desired alloy composition.

Processes are disclosed for forming beryllium-copper metal rings having a fine and uniform grain structure. A raw BeCu casting is pre-forged and turned to form a BeCu billet. The BeCu billet is subjected to various heat treatment and cooling cycles to obtain/maintain combinations of advantageous material properties. Generally, the BeCu billet is preheated, hot worked via forging, heated again, hot worked again via ring rolling followed by air cooling, solution annealed followed by quenching, and heated a final time followed by air cooling.

A gas blower device for blowing gas onto a surface of a traveling strip includes a plenum in the form of a hollow box for containing gas and comprising two side surfaces, a back surface and a front surface opposite to the back surface. The front surface having a profile of convex type symmetry with respect to a mid-plane perpendicular to the plane of the strip, so that a middle ridge of the front surface is located at the smallest distance from the plane of the strip. The front surface further presenting multiple tubular nozzles protruding at the front surface and having a gas outlet orifice facing in use the traveling strip. All the outlet orifices are essentially in a plane parallel to the strip plane. The gas blower device further includes a gas intake tube for feeding the plenum with gas.

A method comprises providing a molten aluminum alloy selected from the group consisting of 6000 series aluminum alloys comprises chromium (Cr) in a range of between 0.001 wt % to 0.05 wt %. The molten aluminum alloy is formed into a formed body having beta-AlFeSi particles. The formed body is solution heat treated at a temperature in a range of 1,025-1,050° F. to form a heat-treated body. The solution heat treating transforms substantially all of the beta-AlFeSi particles into alpha-AlFeSi particles such that the heat-treated body is substantially free of the beta-AlFeSi particles.

Provided herein are systems and methods for producing thick gauge aluminum alloy articles such as plates, shates, slabs, sheet plates or the like.

An aluminium based alloy, and a method for production of components by additive manufacturing (AM) or other rapid solidification process with the alloy, is based on the alloy having a composition with from 2.01 wt % to 15.0 wt % manganese, from 0.3 wt % to 2.0 wt % scandium, with a balance apart from minor alloy elements and incidental impurities of aluminium.

Described herein are methods of processing heat treatable aluminum alloys using an accelerated aging step, along with aluminum alloy products prepared according to the methods. The methods of processing the heat treatable alloys described herein provide a more efficient method for producing aluminum alloy products having the desired strength and formability properties. For example, conventional methods of processing alloys can require 24 hours of aging. The methods described herein, however, substantially reduce the aging time, often requiring eight hours or less of aging time.
