E - longitudinal direction of cut samples; P - transverse; H - height, T - tangential.
Heat resistance is characterized by the creep limit - the greatest stress under the action of which the material at a given temperature deforms by a given amount. The index through the fraction is the deformation and the time in which this deformation occurs.
Heat resistance of titanium bar VT22
| Bar | Thickness (mm) | Heat treatment | t°C | Creep strength (0.2/100) |
|---|---|---|---|---|
| VT22 | 25 | Annealing | 300° | 764 |
| VT22 | 25 | Annealing | 350° | 402 |
| VT22 | 80 | Quenching + aging | 250° | 890 |
| VT22 | 80 | Hardening+aging | 300° | 880 |
The long-term strength is the greatest stress that fractures the material at a given temperature, after a certain time. Naturally, the higher the temperature and the longer the load duration, the lower the tensile strength.
