摘　　要：文章采用扫描电镜技术分析易拉罐用3104铝合金在深冲过程中罐体断裂行为。研究发现合金板材中的分层是导致易拉罐罐体断裂的主要原因。板材分层主要是由于铸造过程中的显微疏松造成的,可通过采取调整浇铸速度等工艺参数减少以至于杜绝该缺陷的产生,从而减低断罐率,提高成品率。Fracture behavior of aluminum alloy 3104 used in cans during deep drawing is studied by Scanning Electron Microscopy.The delamination in the alloy sheet is one of the reasons for the cracking of the cans.The delamination of plate is mainly caused by the microporosity in casting.Microporosity can be eliminated by adjusting the casting speed and other technological parameters,thus reducing the rate of cracked can,and improving the rate of finished product in the meanwhile.
