In application form, an armor structure is provided that is suitable for protecting against ballistic projectiles.

Abstract: The present invention relates to a component of a concrete delivery system comprising a substrate made of relatively thin gauge carbon steel or aluminum, and a protective coating of amorphous, nano or near-nanoscale steel, or mixtures thereof, overlying the substrate, wherein the coating may be formed by thermal deposition process from multi-component glass forming steel alloys. The protective coating may also be heat treated to increase wear life.

Abstract: The present disclosure relates to an iron alloy sheet comprising ?-Fe, and/or ?-Fe phases wherein the alloy has a melting point in the range of 800 to 1500° C., a critical cooling rate of less than 105 K/s and structural units in the range of about 150 nm to 1000 nm.

Abstract: The present invention relates to the addition of niobium to iron based glass forming alloys. More particularly, the present invention is related to changing the nature of crystallization resulting in glass formation that may remain stable at much higher temperatures, increasing the glass forming ability and increasing devitrified hardness of the nanocomposite structure.

Abstract: A method of controlling or containing radioactive contamination by providing a neutron absorbing material to a radioactive contamination site. Preferably the neutron absorbing material is present as a powder, granule, slurry or suspension, allowing the neutron absorbing material to blanket cover the radioactive contamination site. Suitable neutron absorbing materials include lanthanide elements having a cross section of 100 Barns or greater, as well as hafnium, zirconium, tantalum, silver, indium, and hydrogen.

Abstract: According to the present invention, the kinetic conditions (i.e. temperature and time) related to how metal glass alloys are transformed are manipulated to alter the microstructure and the resulting properties of the subject alloys. Low temperature recovery, relaxation, crystallization, and recrystallization phenomena are used to shift the microstructure of amorphous or partially crystalline coatings in order to tailor and improve their properties for specific applications.

Abstract: A method is provided for forming a metallic overlay having enhanced toughness. The metallic overlay may be a weld, a metallic coating, or similar application. The method includes applying a glass forming metallic alloy to a substrate while the alloy is in a molten or semi-molten state. At the interface of the metallic alloy overlay and the substrate the substrate metal becomes at least partially molten and combines with the alloy to form metallurgical bonds. When the metallic alloy cools it experiences a high relative degree of thermal contraction. The metallurgical bonds between the substrate and the alloy constrain the contraction of the alloy at the interface with the substrate. This results in the inducement of compressive stresses in the metallic alloy overlay. The induced compressive stresses inhibit the formation of cracks in the overlay and/or mitigation of the effects of any cracks in the overlay.

Abstract: The present application relates to iron based glass forming alloys and their manufacture in powder, cored wire and stick electrode form to produce feedstock for a wide variety of weld overlay hardfacing application techniques. The alloys when welded form structures which are extremely hard and correspondingly extremely wear resistant. The novel approach of these alloys allow the replacement of conventional high hardness and wear resistant hardfacing alloys which are often composite materials made up of a binder and hard particles such as carbides, borides, borocarbides, nitrides, etc.
