Synthesis behavior of nanocrystalline Al–Al2O3 composite during low time mechanical milling process

In this work, four different volume fractions of Al2O3 (10, 20, 30 and 40 vol.%) were mixed with the fine Al powder and the powder blends were milled for 5 h. Scanning electron microscopy analysis, particle size analysis and bulk density measurements were used to investigate the morphological changes and achieving the steady state conditions. The results showed that increasing the Al2O3 content can provide the steady state particle size in 5 h...
