Abstract

The temperature dependences of the internal friction, Q −1, of vanadium and of V-(0.3–10%) Ti alloys are measured in the range from room temperature to 900°C. Three peaks at 227, 295, and 375°C attributed to the O-V, O-Ti, and Ti-V complexes are detected for the alloys with a low content (<5%) of titanium. In the alloys containing 5–10% titanium, these peaks disappear, but a new peak attributed to the V-O-Ti complex arises at 475°C. The binary complexes are found to make the main contribution to retardation of dislocations in the V-Ti alloys with a low content of titanium and, consequently, to strengthening and embrittlement of these alloys.
