Conclusions

  1. 1.

    The phase composition, structure, and Tk of the alloys V3.04(Ge1−xFex)0.96 with x =0, 0.1, 0.2, 0.3 are investigated.

  2. 2.

    It is shown that solid solutions with the preferred displacement of the V atoms by the Fe atoms are formed after smelting, while the iron atoms are localized in the germanium sublattice after annealing at 800°C.

  3. 3.

    The hypothesis about tetragonal distortion of the V3.04Ge0.96 lattice after the insertion of iron is expressed.

  4. 4.

    The hypothesis about the governing role of chains of transition-metal atoms in the formation of Tk is confirmed.
