The method for preparation of nanostructured Cu80Fe20 composites was developed. The Fe particles with sizes about 60-70 nm are dispensed in Cu matrix. The magnetic resistance of composites at 20 0C and in electromagnetic field of 14 kE equals (-0,95 %). The monolithic TiH2 - Ni3Tі and TiH2 - Al3Tі composites with increased in 2 times hardness were obtained by destructive hydrogenizing of fused TіNі and Ti3Al intermetallic plates. After recombination their by annealing in vacuum or in hydrogen the ordered composites with increased hardness and hardness-modulus of elasticity relation were obtained. Detonation coats from the treated in H2 Ti3Al powder have the increased coat-substrate mechanical adhesion. The method for preparation of Fe-Y2O3 and Cu - Al2O3 composites were developed. The oxide particles equal about 50-70 nm. The maximal dispersion of Y2O3 particles were obtained when YH3 as initial substance was used. Decreasing of the particle sizes to some nanometers increased the mechanical properties of compounds to two-five times. The extrapolation value of the long-time strength of Fe+3%Y2O3 at 550 0С and loading 100 MPa is equal ~300 h.
