Conclusions

  1. 1.

    The tensile strength σv (130 kg mm2) and microhardness HV (350 kg/mm2) of 08kp steel-Ag multilayer composite materials (MCM) substantially exceed both σv and HV of alloy mixtures of the same composition (65 and 150 kg/mm2, respectively) and σv and HV of 08kp steel (90 and 180–200 kg/mm2, respectively).

  2. 2.

    The gain in strength Δσv due to the work-hardening induced by rolling with a reduction of 70% is 95 kg/mm2 for the MCM, compared with 40 and 10 kg/mm2 for the steel and silver, respectively.

  3. 3.

    The coercive force HC of the MCM (48 Oe) is many times that of alloy mixtures of the same composition (8 Oe) or of 08kp steel (1–2 Oe).

  4. 4.

    Reducing the layer thickness to less than 100 Å transforms the composite into a powder type material with a flaky structure. During the rolling of such a material, the flakes slide over one another, and both the thickness of the material and its properties remain unchanged.
