Abstract
The shape, dimension, and microhardness of Al-2Cu-1,6Mn-0,4Zr (wt. %) based composite material powders hardened by nanodiamond particles in amount of 0–10 vol. % depending on mechanical alloying duration have been investigated. The maximum run time in planetary ball mill is 15 h. Mean pellet size of composite materials obtained with the use of chip matrix particles of 1000 μm in size is shown to decrease up to 30 μm when mechani- cal alloying time increases. In the course of mechanical alloying the material microhardness rises to 270–320 HV.
