To achieve this objective, the powder was obtained by manually mixing the APT and copper nitrate and reducing under a hydrogen atmosphere at 800 °C and then compacting at 500 MPa and sintering in a tubular furnace at 1200 °C for 60 minutes. The obtained materials were characterized by XRD, SEM, EDS, particle size analysis, density and microhardness measurements. The composite powder showed a good homogenization of Cu in W with very fine and agglomerated particles and a mean crystallite size of 25.64 nm. SEM coupled with EDS with mapping analysis revealed a homogeneous distribution of Cu and W in the sintered sample. The composite had a relative density of 96.77% and a microhardness of 523.66 HV. Therefore the method of obtaining the composite powder is feasible to sinter W-30 wt% Cu powder due to a greater dispersion and homogenization of phases and the average particle size.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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
