Abstract

The Cu–W pseudoalloys with 2–10 vol.% of nanosized tungsten particles (30–40 nm) are studied. The bulk samples with relative density up to 99.1–99.6% were produced by shock pressing. The introduction of nanosized tungsten particles increased the pseudoalloy strength to 2,7НСu with insignificant reduction in plasticity (δ = 13%) and electroconductivity (to λ = = 0.875% IACS for the pseudoalloy with 10 vol.% W). The microstructures of the Cu–W pseudoalloys are analyzed.
