The present invention provides a method for producing a consolidated article composed of a transition metal alloy. The method includes the step of selecting a rapidly solidified alloy which is at least about 50% glassy. The alloy is formed into a plurality of alloy bodies, and these alloy bodies are compacted at a pressing temperature of not more than about 0.6 Ts (solidus temperature in °C.) to consolidate and bond the alloy bodies together into a glassy metal compact having a density of at least about 90% T.D. (theoretical density). The compacted glassy alloy bodies are then heat treated at a temperature generally ranging from about 0.55-0.85 Ts, but, in any case, above the alloy crystallization temperature, for a time sufficient to produce a fine grain crystalline alloy structure in the compacted article.

A method for producing a consolidated metal article, comprising the steps of: (a) selecting a rapidly solidified alloy, which is at least 50% glassy; (b) forming said alloy into a plurality of alloy bodies; (c) compacting said alloy bodies at a pressing temperature of not more than about 0.6 Ts (solidus temperature measured in °C.) and at a pressure sufficient to bond said alloy bodies together into a glassy metal compact having at least about 90% T.D.; and (d) heat treating said compacted alloy bodies at a heat treatment temperature ranging from about 0.55-0.85 Ts for a time period sufficient to provide a crystalline alloy consolidated article.
