FIELD: metallurgy.
SUBSTANCE: production of metal-matrix composite is performed with mechanical alloying matrix material, hardening particles and 0.05 10 vol. % nano particles of hardness exceeding matrix of metal-matrix composite and with maximal dimension as high, as 50 nm. Ratio of average dimension of added nano particles to source average dimension of hardening particles does nor exceed 0.1.
EFFECT: upgraded quality of composite due to uniform distribution of hardening particles in matrix and increased output of acceptable product due to reduced or complete elimination of treated materials balling and sticking on process equipment.
