摘要
Abstract
In situ Al2O3 decomposed from Al2(SO4)3 reinforced aluminum matrix composites was fabricated through stirring cast by adding Al2(SO4)3 to the molten alloy which is the raw and processed materials from which industrial high purity Al2O3 is made. Not only production cost may be reduced but also SO3 decomposed from Al2(SO4)3 may refine and remove the gas from the molten composites by the way stated before. As a result, Al2O3 and matrix bonded well, no cast defects being found, such as gas hole, porosity and particles segregation in in situ Al2O3 decomposed from Al2(SO4)3 reinforced aluminum matrix composites It is considered the key fact of particulate reinforced aluminum matrix composites really being produced in industrial that SO3 decomposed from Al2(SO4)3 may refine and remove the gas from the molten composites.关键词
