Conclusions

  1. 1.

    Rapid quenching of binary alloys of Cu with 5–15% REM at a rate of 5·104–8·106 °C/sec leads to preparation of highly dispersed microcrystalline and amorphous-crystalline tapes with a thickness of 35–50 μm distinguished by increased strength, hardness, and specific electrical resistivity.

  2. 2.

    Rapidly quenched alloys of copper with 5–15% REM contain a metastable supersaturated solid solution based on copper with a fcc-lattice, metastable M-phase, and an amorphous phase whose amount is governed by the nature of the specific alloying component (REM) and the melt cooling rate (more than 105 °C/sec).

  3. 3.

    Metastable M-phase on heating at rate of 0.3°C/sec at 300–350°C is converted into equilibrium compounds of the corresponding systems.
