    摘要: Alloys having compositions similar to commercial tool steels, but modified by the addition of 0.1 to 1.5 wt. % boron are disclosed. The alloys are subjected to a rapid solidification processing (RSP) technique, producing cooling rates between 10.sup.5 -10.sup.7 .degree.C./sec. The as-quenched RSP ribbon or powder, etc. consists essentially of a single phase with a body centered cubic structure. After selected heat treatments, the rapidly solidified alloys have a microstructure consisting of ultrafine metallic carbides and metallic borides dispersed in an iron rich matrix and thus have high hardness, wear resistance and high-temperature stability. These final structures have improved properties for applications, e.g., where standard high speed tool steels are now utilized.

    摘要: Alloys, of iron, cobalt, nickel and chromium containing both metalloids and refractory metals are disclosed. The alloys are rapidly solidified at cooling rates of 10.sup.5 -10.sup.7 .degree. C./sec so as to produce an ultrafine grained metastable crystal structure having enhanced compositional homogeneity. The as-quenched metastable alloys are brittle, permitting pulverization, if desired. Heat treatment is used to convert the metastable brittle alloys into ductile alloys with primary grains of ultrafine grain size which contain an ultrafine dispersion of boride as well as carbide and/or silicide particles. The powders or ribbons can be consolidated into bulk parts. The heat treated alloys possess good mechanical properties, in particular high strength and hardness, as well as good corrosion resistance for selected compositions, making them suitable for many engineering applications.

    摘要: A class of amorphous metal alloys is provided in which the alloys are rich in iron, nickel, cobalt, chromium and/or manganese. These alloys contain at least one element from each of three groups of elements and are low in metalloids compared to previously known liquid quenched amorphous alloys rich in iron, nickel, cobalt, chromium and/or manganese. The alloys can be readily formed in the amorphous state and are characterized by high hardness, high elastic limit and, for selected compositions, good corrosion resistance. Products made from these alloys include cutting tools, such as razor blades.

    摘要: A process and apparatus for producing continuous length shaped metal filaments by casting a stream of molten metal within a groove formed in the inner periphery of a cylindrical chill roll. The groove is flanked by a tapered opening of a material which has low thermal conductivity and which is not wetted when contacted by the molten metal. This novel technique increases the tolerance of the position in which the molten stream may be introduced into the groove while ensuring the production of an approximately rounded cross section by preventing the molten stream from spreading out of the groove.

    摘要: Alloys having composition similar to commercial precipitation-hardenable stainless steels, but modified by the addition of 1.4 to 2.4 wt % boron, are disclosed. The alloys are subjected to a rapid solidification processing (RSP) technique which produces cooling rates between .about.10.sup.5 -10.sup.7 .degree.C./sec. The as-quenched RSP ribbon or powder, etc., consists primarily of a metastable crystalline solid solution phase. The metastable crystalline phases are subjected to suitable heat treatments so as to produce a transformation to a stable multiphase microstructure, which includes borides; this heat treated alloy exhibits superior mechanical properties and thermal stability in conjunction with good corrosion and oxidation resistance.

    摘要: A method of fabricating aluminum alloys containing finely dispersed aluminum-transition metal intermetallic phases is disclosed. The alloys are subjected to melt spinning to form a brittle filament consisting in large measure of a metastable face-centered cubic solid solution; this is then pulverized to a staple or powder configuration; the power or staple is consolidated using conventional techniques. Upon heat treatment, the solid solution decomposes into a structure consisting of an aluminum alloy matrix of conventional composition containing a fine uniform dispersion of the intermetallic phase, the heat-treated alloy being ductile. The heat-treated alloys possess high strength, especially at elevated temperatures. Preferred alloys are disclosed which contain 10 to 15 wt % Fe.
