Abstract

In the present paper, preparation of nanocomposite powders of mutually immiscible Fe and Cu metals with different Fe-to-Cu ratios by electric explosion of wires and their processing into bulk materials are reported. Near-fully dense nanocrystalline Fe–Cu specimens with high compressive and bending strengths are obtained by high pressure consolidation/cold sintering of the electrically exploded powders at 3 GPa. Reduction treatment in an H₂-flow prior to consolidation results in an intimate contact between the oxide free powder surfaces and in an excellent inter-particle bonding integrity. The Cu-rich composition exhibits an attractive combination of high strength and relatively low electrical resistivity.
