Abstract
In this study, the effect of Ta, V and Ti in W matrix on characteristics and synthesis of the model alloys
were investigated. The secondary ball milling method and in-situ Y dispersed oxides were used to further
improve material properties. The results showed that the model alloys adding with the V element could
facilitate the grain refinement and microstructure homogeneity of the tungsten alloys. The (Ta,V)-rich
and V-rich oxides were found in the microstructure and have been identified as the TaVO4 and V2O5
phases. The nano-scale of the in-situ oxide particle YTaO4 was observed and coherent with the tungsten
matrix. Moreover, the secondary ball milling method was effective to refine the microstructure and to
increase the relative density and mechanical properties.
