Conclusions

  1. 1.

    The surface state of the initial surface has a great effect on the elastic aftereffect of microfoils made of magnesium bronze Br. Mg 0.8. The elastic aftereffect in microfoils made of wires with oxidized surfaces is several times higher than foils made from wires from which the oxide layer has been removed.

  2. 2.

    The presence of oxide layers formed during heat treatment on the surface of Br. OTs 4-3 and MR47-VP microfoils considerably increases the elastic aftereffect; this increase is 15–20 times for Mr47-VP and 30–40% for Br. OTs 4-3.

  3. 3.

    The oxidation of the surface of microfoils of Br. Mg 0.8 magnesium bronze and of the K40NKhMV alloy during heat treatment does not change their elastic aftereffect.

  4. 4.

    In microfoils of all the alloys investigated the magnitude of the elastic aftereffect does not change after the foils are kept in the corrosive medium.
