Composition and application
Titanium VT3−1 refers to heat-resistant two-phase alloys based on titanium. Due to the presence of chromium and molybdenum, the metal is characterized by increased thermal stability at high temperatures, and the presence of aluminum provides the alloy with sufficient ductility. At the request of the customer can also be made in the form of forgings. The operating temperatures of application are up to 400… 450 0 C. With thermal treatment and subsequent aging, the heat resistance of VT3−1 alloy can be increased to 530 ° C. The presence of aluminum reduces the density of the alloy, stabilizes and strengthens the α phase, while chromium and molybdenum provide increased the amount of more ductile β-phase for hot working. The VT3−1 alloy is popular with the high value of creep resistance at 300 ° C, and also the fatigue strength.
One of the difficulties with the β phase, which has a body-centered cubic crystal structure, is that, like the ferritic iron, it has a temperature of plastic brittle transition. The transition temperature tends to be above room temperature, and fracture cracking dominates at ambient temperature. Therefore it is developed and starts to be actively used
powder metallurgical variant of this alloy containing small concentrations of boron and carbon with about 25% greater strength and modulus of elasticity, but much less plasticity. The presence of chromium provides an alloy, heat resistance up to 510 ° C, so it is used in the manufacture of aircraft engines.
The chemical alloy of the alloy, which meets the technical requirements of GOST 19807−91, is presented in the table (numerical data — in percent, titanium — base):
|0.2 — 0.7||Not more than 0.1||0.15 — 0.4||0.8 — 2||2 — 3||Not more than 0.05||5.5 — 7||Not more than 0.5||Not more than 0.15||Not more than 0.015||Do0.3|
