喷射成形AlSn20Cu合金靶材制备工艺与组织控制研究

喷射成形AlSn20Cu合金靶材制备工艺与组织控制研究摘要：本文研究了喷射成形AlSn20Cu合金靶材制备工艺与组织控制方法。采用柔性制模技术制备了20mm×20mm×3mm的AlSn20Cu靶材，采用X射线衍射仪、SEM、热电偶仪等测试工具对其组织结构、物理力学性能进行了分析。结果显示，合金中的Sn、Cu元素共晶固溶度限制了晶粒尺寸的增加，但粗大的铜基本不溶于铝，利于增大晶粒尺寸；液相成分的增加导致了晶粒尺寸的尺寸的增加和形态的变化。在各种成形参数和阴阳极条件下，经过优化工艺，制备得到了晶粒较大、均匀的AlSn20Cu靶材，其显微组织为均匀的细晶粒+富含Sn的粗晶组织，力学性能优异，证明了该工艺具有广泛的应用前景。
