Conclusions

  1. 1.

    Rolling at 20, 150, 450, and 495° leads to an increase in the hardness of alloy D16 during aging at 180–200° as compared with the undeformed condition. The largest hardening effect is observed after deformation of 25% at 20° and 12% at 150°. In the latter case the increase in hardness is more resistant at high temperatures.

  2. 2.

    The substantial increase in strength due to LTMTT is accompanied by considerable reduction of the ductility. Deformation at 150° induces a better combination of properties than cold deformation. HTMTT, unlike LTMTT, increases the strength of alloy D16 to a lesser extent and leads to somewhat higher values of the ductile and toughness characteristics.

  3. 3.

    Plastic deformation at 150°, and especially high-temperature deformation, improves the corrosion resistance of alloy D16 after aging.
