摘要： The invention provides an aluminum based alloy consisting essentially of the formula Al.sub.bal Fe.sub.a X.sub.b, wherein X is at least one element selected from the group consisting of Zn, Co, Ni, Cr, Mo, V, Zr, Ti, Y and Ce, "a" ranges from about 7-15 wt %, "b" ranges from about 2-10 wt % and the balance is aluminum. The alloy has a predominately microeutectic microstructure. The invention also provides a method and apparatus for forming rapidly solidifed metal, such as the metal alloys of the invention, within an ambient atmosphere. Generally stated, the apparatus includes a moving casting surface which has a quenching region for solidifying molten metal thereon. A reservoir holds molten metal and has orifice means for depositing a stream of molten metal onto the casting surface quenching region. A heating mechanism heats the molten metal contained within the reservoir, and a gas source provides a non-reactive gas atmosphere at the quenching region to minimize oxidation of the deposited metal. A conditioning mechanism disrupts a moving gas boundary layer carried along by the moving casting surface to minimize disturbances of the molten metal stream that would inhibit quenching of the molten metal on the casting surface at a quench rate of at least about 10.sup.6 .degree. C./sec. Particles composed of the alloys of the invention can be heated in a vacuum and compacted to form a conslidated metal article have high strength and good ductility at both room temperature and at elevated temperatures of about 350.degree. C. The consolidated article is composed of an aluminum solid solution phase containing a substantially uniform distribution of dispersed intermetallic phase precipitates therein. These precipitates are fine intermetallics measuring less than about 100 nm in all dimensions thereof.

A high-energy stream, such as a laser or electron beam, may be selectively directed towards a precursor material to melt a portion of the precursor material in a localized region. The molten precursor material is cooled at a rate of greater than or equal to about 1.0×105 K/second to form a solid high-strength, lightweight alloy component comprising a stable ternary cubic phase having high heat resistance and high strength. The stable ternary phase may be AlxFeySiz, where x ranges from about 4 to about 5 or about 7.2 to about 7.6, y is about 1.5 to about 2.2, and z is about 1. The stable ternary phase may also be Al6Ni3Si. Materials and components, such as automotive components, made from such methods are also provided.

摘要： A method of forming a bulk metallic glass is provided. The method includes overheating the alloy melt to a temperature above a threshold temperature, Ttough, associated with the metallic glass demonstrating substantial improvement in toughness compared to the toughness demonstrated in the absence of overheating the melt above Tliquidus, and another threshold temperature, TGFA, associated with the metallic glass demonstrating substantial improvement in glass-forming ability compared to the glass-forming ability demonstrated in the absence of overheating the melt above Tliquidus. After overheating the alloy melt to above Ttough and TGFA, the melt may be cooled and equilibrated to an intermediate temperature below both Ttough and TGFA but above Tliquidus, and subsequently quenched at a high enough rate to form a bulk metallic glass.
