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.

The present invention relates to a method for producing metal-comprising geometrically complex pieces and/or parts. The method is specially indicated for highly performant components. It is disclosed a method for the production of complex geometry, and even large, highly performant metal-comprising components in a cost effective way. The method is also indicated for the construction of components with internal features and voids. The method is also beneficial for light construction. The method allows the reproduction of bio-mimetic structures and other advanced structures for topological performance optimization.

A reinforced alloy comprising reinforcement particles (fine and/or coarse) for a bracket that provides enhanced theft deterrence and lightweight. The bracket may be used for a lock for a personal transportation vehicle.

Systems and methods of non-contact tensioning of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor. The magnetic rotor is spaced apart from the metal strip by a first distance. The systems and methods also include tensioning the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is tensioned in an upstream direction or a downstream direction. In other aspects, rotating the magnetic rotor induces a magnetic field into the metal strip such that a force normal to a surface of the metal strip is applied to the metal strip.

Described herein are 6xxx series aluminum alloys with unexpected properties and novel methods of producing such aluminum alloys. The aluminum alloys are highly formable and exhibit high strength. The alloys are produced by continuous casting and can be hot rolled to a final gauge and/or a final temper. The alloys can be used in automotive, transportation, industrial, and electronics applications, just to name a few.

Systems and methods of pre-ageing of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor of a reheater. The systems and methods also include heating the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is heated.

Disclosed are mixtures for use in additive manufacturing, wherein the powder mixture comprises first and second materials. The first material includes a metal alloy or a mixture of elemental precursors thereof, and is in powder form. The second material includes a reinforcement material comprising powder particles having a particle diameter of from 1 to less than 30 μm (as determined by laser scattering or laser diffraction). The inventive powder mixtures allows for the processing to three dimensions objects which are free of cracking and which thus have favourable mechanical characteristics. Further disclosed are processes for the preparation of corresponding powder mixtures and three dimensional objects, three dimensional objects prepared accordingly and devices for implementing processes for the preparation of such objects, as well as the use of a corresponding powder mixture to suppress crack formation in a three-dimensional object, which is prepared by additive manufacturing.

Provided is a performance controlling method for a high-strength aluminum alloy shell during an ultra-low temperature forming process. The present disclosure greatly improves the performance of an aluminum alloy sheet by applying an ultra-low temperature. The present disclosure cools the aluminum alloy sheet to an ultra-low temperature by using an ultra-low temperature cooling medium, so as to compensate for insufficient hardening caused by insufficient deformation and avoid cracking caused by increased deformation. The present disclosure cools the sheet blank zonally according to a deformation law of a desired curved part, and controls the ultra-low temperature distribution of the sheet blank during forming so as to promote the formation of a substructure in a small-deformation zone. In this way, the present disclosure improves a subsequent age-hardening effect, and corresponding uniformity of microstructure and performance, and effectively solves the problem of non-uniformity due to uneven deformation.

Systems and methods of threading a metal substrate on a rolling mill include receiving a coil of the metal substrate. The method also includes uncoiling the metal substrate from the coil while the coil and guiding the metal substrate to a work stand of the rolling mill with a threading system.
