Traditional and single shielding material has not satisfied the demand for radiation protection. Shielding materials with a good comprehensive performance have attracted attention. W–Ni–Fe alloys with different Ni/Fe ratios have been prepared through liquid phase sintering using W, Ni and Fe elementary powders. The microstructure, morphology and fracture appearance of such prepared W–Ni–Fe alloys with different Ni/Fe ratios were analysed with the SEM and metallographic test. The effects of the Ni/Fe ratio on the density, microhardness, tensile strength and shielding eff...
