摘要(Abstract)：

利用扫描电子显微镜(SEM)、透射电子显微镜(TEM)和X射线衍射(XRD)等方法研究了不同复合热处理(深冷处理+均匀化处理)工艺对再生3104铝合金的微观组织影响。XRD图谱表明,深冷处理使3104铝合金基体(200)晶面衍射峰相对强度升高甚至超过(111)晶面成为最强峰。经均匀化处理后,粗大析出相逐步溶入基体,部分最终呈粒状断续分布在晶界上,基体中也出现大量片状Al6Mn析出相。经先深冷处理后均匀化处理的再生3104铝合金中Al6Mn相尺寸最小,为(3.25±1.18)μm,在基体中分布也更加均匀,这主要是由于在深冷处理过程中产生大量位错,为析出相的扩散、形核提供了通道和形核核心。
