Conclusions

  1. 1.

    The optimal combination of fracture toughness, fatigue limit, and strength characteristics of D16 alloys can be obtained from semifinished products with a primarily unrecrystallized structure and with the copper and magnesium concentrations near the lower limit, and possibly by reducing iron and silicon impurities.

  2. 2.

    The amount of manganese should be minimal but sufficient to obtain a preferentially unrecrystallized structure under given conditions of hot deformation. The deformation during straightening should be held to the minimum within the limits of the given OST.
