Conclusions
-
1.
The characteristics of static and cyclic strength of titanium alloys VT22 and VT37 with solid-solution hardening are 20–25% higher than in high-temperature alloys with intermetallic hardening.
-
2.
The use of titanium alloys VT22 and VT37 instead of the traditional high-temperature alloys (VT3-1, VT-6) for the production of large disks and engine blades serving at 300–350°C makes it possible to reduce their mass by 20–25%.
