Abstract

In the present work the Al2O3 content (0, 5, 10, 15 wt%) and ANNEALING effect on the microstructural properties of Al-10Mg alloy was investigated. The milling process of the composites was carried out under argon atmosphere. Milled powders were pressed and annealed at 400°C for 45 min. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) devices were applied to microstructural and phase transformations studies of the prepared composites. The results show that the MECHANICAL ALLOYING process accelerates due to alumina content increment and it results in the formation of a steady-state condition. The alumina increasing cause to decrement of the matrix grain size from 32 to about 15m before ANNEALING and it prevent the abnormal grain growth after ANNEALING. Increasing in the grain size occurs after ANNEALING process due to the particles agglomeration. Also, grain growth, lattice strain decrement and lattice parameter decrement were observed as a result of recrystallization. The microstructural did not show significant changes for the samples with high quantity of alumina. Formation of Al3Mg2 phase after ANNEALING, observed at the X-ray patterns, can prevent from further grain growth.
