The alloys doped by iron has lower disproportionation pressure equal 1,1 and 0,6 MPa for х=3,91 and 5,95 at/f.un., accordingly. After HDDR the alloys enclose the Fe-Co solid solution fibres with 180-450 nm diameters and 30 nm in length and ferromagnetic phase with Th2Zn17-type structure with 40-200 nm grain size. The vanadium content alloys disproportionats under 3-4 MPa hydrogen pressure at 700 °C during 1 h reaction time. The ferromagnetic phase grain size after HDDR equal 70-250 nm, and the Fe-V solid solution fibres has 200-700 nm in diameter.
