International Classification:
B32B 3/12, B32B 3/20, B32B 3/00, B32B 3/06, E04D 3/36
US Classification:
428116, 428118, 428119, 428188, 428327, 428 72, 4283073, 428177, 428192, 26417712, 264630, 523021, 52 60
Abstract:
Multi-layered cellular metallic glass structures and methods of preparing the same are provided. In one embodiment, the cellular metallic glass structure includes at least one patterned metallic glass sheet and at least one additional sheet. The at least one patterned metallic glass sheet may include multiple sheets connected together to form a group of sheets, and the structure may include a group of sheets sandwiched between two outer sheets. The patterned metallic glass sheets may be patterned by thermoplastically forming two- and/or three-dimensional patterns in the metallic glass sheets. The metallic glass cellular structures are useful in a wide variety of applications, including but not limited to blast protection applications, energy absorption applications, structural support applications, biomedical implant applications, heat exchanger applications, thermal management applications, electrical shielding applications, magnetic shielding applications, and debris and radiation shielding for aerospace and outer space applications.
Foams Made Of Amorphous Hollow Spheres And Methods Of Manufacture Thereof

International Classification:
B29C 44/38, B32B 38/10, C03C 25/68
US Classification:
156 622, 216 34, 156281
Abstract:
Novel cellular solids and foams from amorphous materials with a glass transition temperature (T) and methods of forming such materials are provided. In particular, foams are formed by expanding or compressing hollow spheres made of a high strength amorphous material, which is defined as a material having high strength characteristics, but also possessing a glass transition within a confined space. Using such a method, it has been unexpectedly found that it is possible to make cellular structures, including both open and closed cell foams, with customizable properties from materials that have been inaccessible with conventional methods. Moreover, based on calculations high specific strengths and stiffnesses are expected.
Composite Penetrator
US Patent:

International Classification:
F42B 1274
US Classification:
148403
Abstract:
A composite penetrator has a plurality of dispersed high aspect ratio bodies of refractory heavy metal such as tungsten wires. A matrix of metal surrounds and wets the dispersed bodies for forming an integral penetrator. The matrix metal is characterized by having localized shear band deformation when strained. The heavy metal is selected from the group consisting of tungsten, tantalum, hafnium, uranium and alloys thereof. A variety of matrix alloys may be used which will remain amorphous or microcrystalline in an object as large as the penetrator when cooled from the molten state. An exemplary amorphous alloy comprises 41. 25 atomic percent zirconium, 41. 25% titanium, 13. 75% copper, 12. 5% nickel and 22. 5% beryllium.

International Classification:
C22F 1/08, C22F 1/14
US Classification:
148522, 148561
Abstract:
Methods and compositions for a novel metal-to-metal or material-to-material joining technique using bulk metallic glasses are provided. The method of the current invention relies on the superior mechanical properties of bulk metallic glasses and/or softening behavior of metallic glasses in the undercooled liquid region of temperature-time process space, enabling joining of a variety of materials at a much lower temperature than typical ranges used for soldering, brazing or welding.
