Effect of Ti, Zr, and Cu content on the microstructure and properties of 2195 Al-Li alloy weldment

2195 Al-Li alloy was welded using six kinds of weld filler wires with different contents of zirconium, titanium, and copper. The S2503 weld demonstrated fine α -Al/Al 2 Cu/Al 3 (Ti, Zr) microstructure and superior mechanical properties. The addition of Zr and Ti refined the grain and modified the so...
