Polycrystalline materials are prepared by electrodeposition of a precursor material that is subsequently heat-treated to induce at least a threefold increase in the grain size of the material to yield a relatively high fraction of 'special' low &#x3a3; grain boundaries and a randomized crystallographic texture. The precursor metallic material has sufficient purity and a fine-grained microstructure (e.g., an average grain size of 4 nm to 5 &#x3bc;m). The resulting metallic material is suited to the fabrication of articles requiring high mechanical or physical isotropy and/or resistance to grain boundary-mediated deformation or degradation mechanisms.
