Abstract : This report summarizes efforts and accomplishments relative to modeling of the mechanical alloying processing and in synthesis and consolidation of structural materials made by mechanical alloying. Models depicting the extent of deformation and the fracture and welding frequencies of powders subjected to mechanical alloying are encapsulated. A description of an improved attritor processing scheme is given. In addition, we describe the means of synthesizing nanocermets of the Cu-NbC system. The structure and properties of these materials are described, as they are know at this time. Finally, a description of consolidated heavy metals and their properties as they are found when prepared from mechanically alloyed precursor powders is given. (MM)
