Abstract
In the interest of mechanical strength and hardness, metallic bodies desirably contain dispersed particles whose diameter preferably is in the range of 50-10,000 Angstrom. A disclosed method for producing such metallic bodies calls for preparing a solution of mixed salts of elements, removing the solvent, transforming to metallic form, and compacting under pressure. Strength of a resulting metallic body may be further developed by aging and, optionally, cold deformation prior to aging. Use of the disclosed method is indicated especially to produce bodies comprising immiscible elements. For example, when Mo is dispersed in Cu, high strength and electrical conductivity are realized.
