Abstract By using high--purity tungsten powders, titanium powders and TA2 Ti sheet as the raw materials, W--10%Ti alloys were prepared by infiltration and liquid--phase sintering respectively. The density and impurity content of C, N and O in W--10\%Ti alloy were measured. The morphology, composition and microstructure were characterized. The results show that W--10\%Ti alloy prepared by infiltration has a relative density of above 94% and is mainly consisted of Ti--rich $\beta$ solid solution, while the relative density of W--Ti prepared by liquid phase sintering is about 90% and the microstructure is uniform. The W--Ti alloys prepared by both methods have low impurity contents. The formation mechanism of W--10\%Ti alloy by liquid phase sintering was discussed as well.
