Influence of ion irradiation on the superconducting intermetallides of A15 structure

By the ''DOSE'' programme the published results on the ion irradiation of the intermetallides of A15 strUcture were analysed. By some assumption relatively to the Esub(d) displacement threshold energy the dependences of sUperconducting characteristics (critical temperature Tsub(K) width of transition ΔTsub(K)) also the kinetic characteristics (specific electric resistivity rho0) and the structure properties (crystal lattice parameter a0), the parameter of range order S, mean square atom displacement (sup(1/2)) on the integral particle flow were calculated for dose dependence, expresses by a quantity of displacement per atom. It was shown, that the dose was a universal measure of ion irradiation effect on physical properties of intermetallides. The main variation of properties (Tsub(K) decreasing of Nb3Sn, Nb3Ge, Nb3Al, Nb3Si, V3Si and Tsub(k) increasing of Mo3Ge, Mo3Si, rho0, a0, ()sup(1/2) increasing and the decreasing of S of all the compositions) appeared at doses up to 0.1 displ./at
