Abstract: A hard phase material is provided for increasing the hardness of a matrix material and improving the wear resistance thereof. The hard phase material is an aluminum boride material having the structure AlB8-16. The aluminum boride hard phase may be incorporated into a matrix material by mixing particulate aluminum boride with the matrix material and through precipitation of aluminum boride from the matrix material. Materials including the aluminum boride hard phase may be used in coating applications to provide a hard and wear resistant coating. Aluminum boride hard phase may also be incorporated into metallurgical products to improve the hardness and wear resistance of the metallurgical products.

Abstract: A nano-crystalline steel sheet and a method of making a nano-crystalline steel sheet are provided. The nano-crystalline steel sheet may be produced by supplying a liquid metallic glass forming alloy to counter-rotating casting rolls. The liquid alloy may form partially solidified layers on each of the casting rolls. The partially solidified layers may then be pressed together by the counter-rotating casting rolls to form a sheet. The twin casting roll method may provide a sufficiently high cooling rate during solidification of the alloy to create a nano-crystalline microstructure.

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: An alloy design approach to modify and improve existing iron based glasses. The modification is related to increasing the stability of the glass, which results in increased crystallization temperature, and increasing the reduced crystallization temperature (Tcrystallization/Tmelting), which leads to a reduced critical cooling rate for metallic glass formation. The modification to the iron alloys includes the additional of lanthanide elements, including gadolinium.

Abstract: An alloy suitable for coating metal surfaces is provided in which the alloy provides a liquid melt which contains a fraction of dissolved oxide forming additives as deoxidizers. The alloyed combination of elements in the liquid melt resists compound formation thus preserving the chemical activity of the individual elements. In a coating application, the alloy may form a coating that can interact with and remove the oxide or residual oxide coating of the base metal to be coated, i.e., scrub the surface of the metal clean. This results in increased coating bond strength and the ability to bond effectively to normally difficult alloys such as stainless steel, refractory metals (W, Ti, Ta etc.), or aluminum alloys which form protective oxide layers.
