general characteristics
Titanium alloys are classified according to the crystal lattice configuration: β-state (in the form of a cube), α-state (in the form hexahedron) and α + β (mixed state). Alloy VT9 relates to α + β alloys, it is doped with 6,4% Al, 3% Mo, 1,5% Zr, 0,25% Si. Designed VIAM v1960 This is the first city of thermally hardened alloy, untapped industry. The first fairly complete work on titanium alloys has been published in 1961 by E. Morozov SG Glazunov and chrome. It shows the test the temperature effect on the mechanical properties of shaped castings of titanium alloy BT3, VT3−1, VT5, VT5−1, VT7, VT8, VT9, VT10. It was found that the highest strength properties in the range of 20 t ° -500 ° C have VT3−1, VT9 alloys.
Titanium Alloy Advantages and application VT9
| Houde. the weight | t ° mp. | properties | Technology | application |
|---|---|---|---|---|
| 4.48 g / cm³ | 980−1020 ° | A high percentage of Al and Si doping gives a higher strength and heat resistance compared to VT6. Designed to operate at a temperature of 400 — 500 ° C. The optimum combination of properties provides a double and isothermal annealing. The content of beta-phase in the annealed alloy is 10%. Alloys thermally hardening quenching and aging. | Satisfactory deformed in a hot state. Manufacturability in the processing pressure is worse than the VT6. Welding is not recommended. | Details GTE:. Blades and disks, and other details of the compressors. |
