Production, sintering, and application of nanocrystalline iron–copper additions in a powder steel

A method is proposed for activated sintering of a sprayed iron powder by the coalescence of pressed particles through fine-grained layers based on iron–copper nanodispersed (ND) additions. The mechanical properties of composite materials containing 2% Fe–Cu ND addition are higher than those of the materials prepared from a mixture of standard powders by a factor of 1.5.
