铝合金2A70棒材粗晶环浅析
Analysis of coarse crystal ring of aluminum alloy 2A70 bar
通过对铝合金2A70特性、金相组织等进行研究，利用金相显微镜、碱浸酸洗低倍、断口等方法分析确定粗晶环形成原因，提出了减少粗晶区形成的控制措施，以提高铝合金产品合格率。
By studying the characteristics of aluminum alloy 2A70 and metallurgical structure, the formation reason of rough crystal ring is determined by means of metallurgical microscope, alkali immersion pickling and fracture, and the control measures to reduce the formation of rough crystal area are proposed to improve the qualified rate of aluminum alloy products.
