Purpose: The aim of this work is to report the effect of the high energy milling processes, on fabrication of aluminium matrix composite powders, reinforced with a homogeneous dispersion of the intermetallic Ti3Al reinforcing particles. Design/methodology/approach: MA process are considered as a method for producing composite metal powders with a controlled fine microstructure. It occurs by the repeated fracturing and re-welding of powders particles mixture in a highly energetic ball mill. Findings: Mechanical alloying, applied for composite powder fabrication, improves the distribution of the Ti3Al intermetallic reinforcing particles throughout the aluminium matrix, simultaneously reducing their size. Observed microstructural changes influence on the mechanical properties of powder particles. Research limitations/implications: Contributes to the knowledge on composite powders production via MA. Practical implications: Gives the answer to evolution of the powder production stages, during mechanical alloying and theirs final properties. Originality/value: Broadening of the production routes for homogeneous particles reinforced aluminium matrix composites.
