dc.description.abstractn this research the mechanical behaviour of pure tungsten (W) and its alloys (2 wt.% Ti─0.47 wt.% Y₂O₃ and 4 wt.% Ti─0.5 wt.% Y₂O₃ ) is compared. These tungsten alloys, have been obtained by powder metallurgy. The yield strength, fracture toughness and elastic modulus have been studied in the temperature interval of 25 °C to 1000 °C. The results have shown that the addition of Ti substantially improves the bending strength and toughness of W, but it also dramatically increases the DBTT. On the other hand, the addition of 0.5% Y₂O₃, is enough to improve noticeably the oxidation behaviour at the higher temperatures. The grain size, fractography and microstructure are studied in these materials. Titanium is a good grain growth inhibitor and effective precursor of liquid phase in HIP. The simultaneous presence of Y₂O₃ and Ti permits to obtain materials with low pores presence.en
