| Summary: | The aim of the current study is to investigate the effect of milling time and speed on mixing
properties of aluminium (Al)/copper (Cu) alloy and Al/Cu composite. Ethanol and argon gas
were employed as process control agent and milling atmosphere. Mechanical alloying process
by means of high-energy ball milling was performed to produce alloy and composite metal
powder. This process proceeds through repeated deformation, cold welding and fracturing of
powder particles mixture with a controlled fine microstructure. X-ray diffraction and particle size
analyser confirmed particle size reduction of Al/Cu alloy with increasing milling time and speed.
On the other hand, the addition of reinforcement particles was found to accelerate the milling
process of Al/Cu composite. Scanning electron microscope micrographs revealed
homogeneous distribution of powder mixture particles by mechanical alloying process at
changing milling conditions. |
