The microstructure and microhardness of W–5wt% Cr alloy fabricated by spark plasma sintering

•The 98.5% relative density W–5wt% Cr alloy was fabricated by SPS method.•The Vickers hardness of the annealed samples can reach 760Hv.•Obtained nano-scaled microstructure may be beneficial for irradiation resistance of W-based alloy. The W–5wt% Cr alloy with a relative density of 98.5% was fabricat...
