| ABSTRACT Growing demands for new emerging materials aimed at introducing nontraditional processes. However, Direct metal oxidation, DIMOX, is applied on Al-alloy, recycling has been prompted to redesign production processes to more cost efficient. Aluminum alloy (scrap) is heated at different temperatures, 950oC, 1000oC, and 1050oC for holding different times (15 to 90 minutes) and then poured into metallic mold. The kinetic of formation of hybrid composite is introduced with the effect of alloying elements addition (a-Fe, and Si). Ceramic alumina phase with intermetallic fibers or whiskers established in a residual aluminum matrix. Functionally graded materials, FGM, is also introduced at prolonged holding time (90 min. at 1050oC). In addition to Scanning electron microscopy with energy dispersive X-ray spectroscopy EDX is utilized for micro-structural characterization. Besides, 3-point test is applied on another group of samples. The application of DIMOX on recycled Al-alloy with the addition of alloying elements has a dominant effect on composite micro-structural characterization. | ||||
