A study was performed on the influence of the formation and distribution of W-rich ({beta}-Ti, W) phase on fracture resistance and hardness of powder-consolidated tungsten-10 wt.% titanium. The effect of density on the mechanical properties was also measured. The flexural stress and strain and hardness linearly increased with increasing density in the density range of 86% to 97% of theoretical density, 14.53 g/cc. In this range the generation of the W-rich ({beta}-Ti, W) was negligible. As the amount of W-rich ({beta}-Ti, W) increased for nearly, fully densified materials, a pronounced drop was found both in the flexural stress and strain. However, the hardness showed no correlation to the amount of W-rich ({beta}-Ti, W) phase present.
