The W–5wt% Cr alloy with a relative density of 98.5% was fabricated by the spark plasma sintering at 1700 °C, subsequently solid solution treated at 500, 800 and 1100 °C for varying times, and then quenched to room temperature. The microstructure and Vickers microhardness were characterized. It was found that after solid solution the grain size increased from 2 to 3.8 μm. The samples annealed at 800 °C for 30–960 min exhibit stable nano-scaled microstructure, that is, the Cr-rich phases in a size of about 100–200 nm precipitated in the W grains by Spinodal decomposition, and the W sub-grains in a size of 40–50 nm separated by the nano-scaled Cr-rich phases. The Vickers microhardness of such samples can reach 760 Hv.
