Abstract |
The study of the structure-phase composition and electrophysical properties of film alloys of molybdenum
and nickel or iron were deposited by the method of simultaneous thermo-vacuum condensation was done. In a
non-annealing state, the samples remain biphasic. After heat treatment at 750 K in vacuum, the formation of
the metastable phases of the fcc-Ni3Mo (lattice parameter a 0.360 nm) and bcc-Fe2Mo (a 0.296 nm) in film
alloys based on Ni and Mo was recorded at concentrations of atoms of ferromagnetic metal 75 and 65 at.% respectively Investigation of the thermoresistive properties of films showed that the dispersion of the structure,
the admixture phases and the solid phase reactions affect the temperature dependence of the resistivity and
the temperature coefficient of resistance. In film alloys, the range of elastic deformation remains greater than
several times than for single-layer metal films, while the strain coefficient is practically unchanged. |
