Conclusions
-
1.
We established the possibility of strengthening alloy VT3-1 by heat treatment (heating at 850–900°, aging at 450–550°), with retention of high ductility and with an even fine-grained equiaxed structure.
-
2.
The mechanical properties of alloy VT3-1 with an equiaxed structure can be improved by MTT (annealing at 800° for 1 h, 1–3% deformation, and aging at 450° for 10 h). The strength characteristics are 8–10 kg/mm2 higher in this case, with retention of satisfactory ductility.
-
3.
The creep resistance of alloys strengthened by heat treatment and mechanicothermal treatment is higher than that of samples annealed only once (with cooling in air).
