A mold apparatus to form a ceramic (or glass) includes a first mold portion having a first coefficient of thermal expansion and a second mold portion having a second coefficient of thermal expansion. In some embodiments, the first mold portion and/or the second mold portion are substantially immiscible with the ceramic material, such as silicon oxide, at a temperature greater than 600&#xb0; C. In some embodiments, the first coefficient of thermal expansion and the second coefficient of thermal expansion are substantially similar to that of the glass or ceramic material. In some embodiments, the first coefficient of thermal expansion is different from the second coefficient of thermal expansion. In some embodiments, the first mold portion and the second mold portion contain a surface coating and a passivation layer.

Mold materials for formed ceramic

The disclosure is directed to Zr and Hf bearing alloys that are capable of forming a metallic glass, and more particularly metallic glass rods with diameters at least 1 mm and as large as 5 mm or larger. The disclosure is further directed to Zr and Hf bearing alloys that demonstrate a favorable combination of glass forming ability, strength, toughness, bending ductility, and/or corrosion resistance.

Zirconium (Zr) and Hafnium (Hf) based BMG alloys

Described herein are methods of constructing a part having improved properties using metallic glass alloys, layer by layer. In accordance with certain aspects, a layer of metallic glass-forming powder is deposited to selected positions and then fused to a surface layer (i.e. layer below) by suitable methods such as laser heating or electron beam heating. The deposition and fusing are then repeated as need to construct the part, layer by layer. In certain embodiments, one or more sections or layers of non-metallic glass-forming material can be included as needed to form a composite final part. In certain aspects, the metallic glass-forming powder may be crystalized during depositing and fusing, or may be recrystallized during subsequent processing to provide selectively crystalized sections or layers, e.g., to impart desired functionality. In other aspects, non-metallic glass-forming materials may be deposited and fused at selected positions, e.g., to provide selective shear banding to impart improved ductile properties and plasticity. In yet other aspects, the metallic glass-forming powder or metallic glass material and non-metallic glass-forming material are deposited and fused to form a foam-like, bellow or similar structure, which is able to crumple under high stress to absorb energy under impact.

Methods for constructing parts with improved properties using metallic glass alloys

Described herein are methods of constructing a part using metallic glass alloys, layer by layer, as well as metallic glass-forming materials designed for use therewith. Metallic glass meshes, metallic glass actuators, three dimensional metallic glass thermal history sensors, and methods of their manufacture are also disclosed.

Metallic glass meshes, actuators, sensors, and methods for constructing the same

Described herein are methods of constructing a three-dimensional part using metallic glass alloys, layer by layer, as well as metallic glass-forming materials designed for use therewith. In certain embodiments, a layer of metallic glass-forming powder or a sheet of metallic glass material is deposited to selected positions and then fused to a layer below by suitable methods such as laser heating or electron beam heating. The deposition and fusing are then repeated as need to construct the part, layer by layer. One or more sections or layers of non-metallic glass material can be included as needed to form composite parts. In one embodiment, the metallic glass-forming powder is a homogenous atomized powder. In another embodiment, the metallic glass-forming powder is formed by melting a metallic glass alloy to an over-heat threshold temperature substantially above the Tof the alloy, and quenching the melt at a high cooling rate such that the cooling material is kept substantially amorphous during cooling to form the metallic glass. In various embodiments, the melt is atomized during cooling to form the metallic glass-forming powder.

Methods for constructing parts using metallic glass alloys, and metallic glass alloy materials for use therewith

A metallic glass part is provided. The metallic glass part includes an alloy core and a metallic glass shell surrounding the alloy core. The alloy core provides compressive force on the metallic glass shell at an interface between the alloy core and the metallic glass shell.

Metallic glass parts including core and shell

An equipment enclosure for housing electronic components includes a front assembly having a front frame, the front assembly defining a front of the enclosure, and a rear assembly having a rear frame. The enclosure further includes at least two side brace members, each side brace member having a first end and a second, opposite end. A first connector is configured to releasably connect the first end of one of the side brace members to the front frame. A second connector is configured to releasably connect the second end of the one of the side brace members to the rear frame. Other embodiments and methods are further disclosed.

Equipment enclosure kit and assembly method

A blanking panel is provided for use with equipment racks or enclosures that house electronic components, and is configured to facilitate installation of the panel with a pair of vertical mounting rails or flanges of a rack or enclosure without the use of tools or other hardware. The blanking panel is constructed of one or more materials and/or defines one or more configurations such that when the blanking panel is installed into a rack or enclosure, portions of a body of the blanking panel interface with a surface of an equipment component or another blanking panel installed above or below the blanking panel to thereby form an air seal there between, which helps to reduce or prevent hot exhaust air from mixing with cooling air within a rack or enclosure, and further helps to reduce or prevent cooling air from bypassing equipment components.
