Abstract: Vitriforming is a method for forming material into complex geometries within a vitreous substance. Liquid material is formed inside the vitreous substance through external forces applied to the vitreous forming medium. This technique can be broken down into four categories of operations: encasement, setup, forming, and extraction. All operations involve a forming medium, and a workpiece. The workpiece can be composed of any material so long as the forming medium is temperature, viscosity, and chemically compatible. The vitreous forming medium translates outside forces into the workpiece to create various geometries. This forming medium can remain a part of the final assembly or get extracted after forming takes place. Workpiece geometry is affected by forming tool geometry, initial setup, heat, and material properties. This process can be used as a fast, efficient means of forming metal or other materials with unique abilities to control material combinations, surface chemistry, texture, and overall geometry.

Abstract: A castable, moldable, or extrudable magnesium-based alloy that includes one or more insoluble additives. The insoluble additives can be used to enhance the mechanical properties of the structure, such as ductility and/or tensile strength. The final structure can be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final structure as compared to the non-enhanced structure. The magnesium-based composite has improved thermal and mechanical properties by the modification of grain boundary properties through the addition of insoluble nanoparticles to the magnesium alloys. The magnesium-based composite can have a thermal conductivity that is greater than 180 W/m-K, and/or ductility exceeding 15-20% elongation to failure.

Abstract: An injection device and method for producing at least one metallic glass part, in which a vertical piston is able to move in a vertical direction, a top end portion of the piston being suitable for being engaged in an injection chamber of a mould linked to a cavity of this mould and open at the bottom; the piston having a top end face on which an element made from metallic glass to be introduced into said chamber can be positioned, the top face of the piston having a concave shape suitable for receiving a bottom portion of the element made from metallic glass. A heating means situated under the mould comprises induction coils, such that, when the piston is in an intermediate position, the majority of the metallic element is situated in the space surrounded by the induction coils.

Abstract: A tastable, moldable, and/or extrudable structure using a metallic primary alloy. One or more additives are added to the metallic primary alloy so that in situ galvanically-active reinforcement particles are formed in the melt or on cooling from the melt. The composite contains an optimal composition and morphology to achieve a specific galvanic corrosion rate in the entire composite. The in situ formed galvanically-active particles can be used to enhance mechanical properties of the composite, such as ductility and/or tensile strength. The final casting can also be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final composite over the as-cast material.

Abstract: A composite material comprising a metal matrix and nanocellulose supplement. The metal matrix is formed of a metal base material and may be monolithic throughout the composite material. The nanocellulose supplement improves a material property of the metal matrix and is formed of a nanocellulose supplement material dispersed in the metal base material. Importantly, the nanocellulose supplement material does not become damaged when the composite material is formed.
