| Resumo: | Title screen This research shows the possibility of obtaining composite W-Cu nanoparticles with the core–shell structure and high content of copper by means of electrical explosion of intertwined W and Cu wires. The use of electric pulse plasma sintering on the obtained W-Cu composite nanoparticles in vacuum in the temperature range 900 °C–1030 °C over 10 min has allowed us to fabricate 3D materials with the relative density of 95.3 ... 98.9% and a conductivity that is close to the theoretical one (63.5%–64.1%IACS). Also, despite a significant content of copper, the microhardness of the 3D material was (2.68–2.7 GPa). High microhardness of the two-phase composite is attributed to its fine-grain structure. The conductivity and microhardness of the 3D W-Cu composite make it a promising material for different electrical engineering applications.
