摘要(Abstract)：

利用光学显微镜和电导率测试仪对3104铝合金不同均匀化条件下的弥散相析出情况进行研究。结果表明,3104铝合金铸锭中只有存在少量Al_(12)Mn_3Si弥散相,均匀化后基体中析出大量Al_(12)Mn_3Si弥散相,呈点状或短棒状,合金电导率升高。随时均匀化温度升高,弥散相发生粗化和回溶,密度减小,尺寸增大,并且合金电导率逐渐降低。因此,经600℃×10 h均匀化弥散相的密度最低,尺寸最大,为400~500 nm。均匀化升温降温速率对弥散相析出有影响,均匀化升温速率减慢,弥散相数量增加,尺寸减小;均匀化冷却速率增加,数量减少,尺寸略有减小;而样品重新在500℃保温2 h后,弥散相数量明显增加,电导率升高,但相互之间差别不大。因此,3104铝合金铸锭在较高温度下(580℃以上)保温较长时间,有利于获得合理的弥散相粒子分布。
