Preparation of Al₂O₃/Al-Si Composites by In Situ Reaction of Fe₂O₃+MnO₂/Al System

Abstract:

Al₂O₃ particles reinforced ZL109 composites were prepared by in-situ reaction between Fe₂O₃+MnO₂ and Al in this paper. The influence of ratio of Mn to Fe on the morphologies of Al-Si-Mn-Fe phase and mechanical properties of the composites was investigated. The microstructure was studied by electron probe micro-analyzer (EPMA) and transmission electron microscopy (TEM). The results show that the Al₂O₃ particles displaced by the Fe₂O₃+MnO₂/Al system are in nanosize. The acicular Al-Si-Fe phases change from acicular to polygonal shape and become smaller with the increase manganese content. The hardness test results have no big difference on the composites. However, the ultimate tensile strength at room temperature and 350°C enhance evidently with the increasing of Mn/Fe.
