Abstract
The oxidation behavior of Al-Si-Mg alloy along with the addition of boric acid particles in the temperature range from 1000℃ to 1200℃ was investigated for aerospace applications. Directly oxidized aluminum with the effect of alloying elements introduced with nontraditional infiltration technique produce both borosilicate particulates and/or fiber structure of reinforced aluminum matrix composite. Two different fabrication processes are utilized either by change of composite constituents weight fraction, or by the fixation weight fraction along with pressureless infiltration technique. Two different approaches introduced for new nontraditional hybrid aluminum matrix composites. The dependence of reinforcement
weight fraction on direct oxidation time and the addition of alloying elements is controlled by pressureless infiltration process. Using recycled aluminum alloy, aluminum alloy containing Si and Mg as matrix induce the synthesis of either particulates and/or fiber in residual aluminum matrix. Boric acid added at 5 % weight fractions either with DIMOX or with
DIMOX and infiltration technique. The obtained results analyzed utilizing optical microscopy, scanning electron microscopy with energy dispersive X-ray spectroscopy, in addition to mechanical characterization. The control of composite ingredients shape, size and uniformity is obtained via nontraditional pressureless infiltration technique. Besides, bulk and Nano borosilicate and carbon fibers are also intrinsically introduced.
