dc.description.abstract | In this work, nanocrystalline Al6063 composite powder reinforced with nanometric oxide ceramic particles was synthesized via an in situ solid-gas reaction during high-energy mechanical alloying under a mixture of argon-oxygen atmosphere. The effect of oxygen volume fraction on the morphological evolution and microstructural changes during mechanical alloying was studied by various analytical techniques including optical and electron microscopy, X-ray diffraction, laser particle size analysis, apparent density measurement, and microhardness test. The reactive mechanical alloying resulted in the formation of amorphous Al- and Al-Mg-Si-Fe oxides with a size range of 40-100 nm and volume fraction up to similar to 2.6 vol.% dependent on the oxygen partial pressure. Electron microscopy studies revealed formation of equiaxed grains with a wide size distribution ranging from 60 to 260 nm. Meanwhile, finer particles with narrower size distribution were achieved at a shorter milling time when the in situ solid-gas reaction was employed. Results of compression test and hardness measurement on the hot extruded powders at 450 degrees C with an extrusion ratio of 14:1 revealed a significant improvement in the mechanical properties caused by the nanometric ceramic particles as well as the ultrafine grain structure of the matrix.
