Abstract

Nanostructured composite powders based on AlMg2 alloy with graphite additives (1–9 wt %) have been obtained by mechanochemical synthesis in a planetary ball mill. Particle size distribution and the specific surface area of powders are measured. X-ray diffraction, Raman spectroscopy, and transmission electron microscopy are used to study the structural and phase composition of the powders. It is established that the hardening of composite powders is caused by the reduction of grain size, as well as by mechanisms of solid-solution and dispersion hardening. These nanostructured composite powders can be used in the manufacture of products by forming techniques and additive technologies.
