铝含量对高铝镁合金凝固组织β相及力学性能的影响
Effect of Al Content on β Phase in Solidification Structure and Mechanical Properties of High-Al Magnesium Alloy
摘要
Abstract
The Al-Mg alloy samples with different content of aluminum were prepared, and the effects of Al content on solidification structure and the morphology of β phase were studied by OM, SEM and EDS. The results reveal that the amount of eutectic β-Mg17Al12 phase rapidly increase with the increase of aluminum content in hypoeutectic composition, and the morphology gradually transformes from mesh sheet structure into cluster structure of eutectic. Brinell hardness of the magnesium alloy first increases and then decreases.关键词
