| 摘 要： | 主要研究在TIG电弧加热条件下，不同焊接参数对Al-Si钎料在钢上的润湿过程中的铺展行为，Al-Si钎料与母材Q235钢的界面冶金行为的影响。通过SEM/EDAX以及热力学方法分析了钎焊接头组织及钎缝的成分分布，研究发现在电弧钎焊条件下，铝/钢界面上容易形成富铝的金属间化合物Fe2Al5,并且随着燃弧时间的增加，Fe2Al5会和Al继续反应生成FeAl和FeAl3，另外2种铁/铝金属间化合物。通过本研究可为铝/钢连接提供理论基础也可为铝/钢制品的轻量化研究提供技术借鉴。

| Abstract: | The spreading behavior of Al-Si filler mctal on Q235 steel and interfacial metallurgy behavior at different brazing parameters are studied under TIG are heating conditions. The joint structure and clement distribution at hrazing seam are also studied by SEM EDAX and thermodynamics mcasures,It can be seen that the Al rich intermetallic compound will form easily at the Al Q235 interface. With the arcing time evolving, the Fe2Al5 compound will react with Al atoms, then intermetallic compound FeAl and FeAl3 are formed at the interface. Research work is valuable in the joining of aluminum and steel. |
