| Abstract: |
| Laser welding of Al-Mg-Sc alloy and LY12CZ has been studied in order to increase the strength properties and corrosion resistance. Microstructure, hardness, tensile strength and corrosion resistance have been analyzed. The experimental results show that using laser welding technology not only can weld alloys but also can get smaller grain size, strength and hardness are higher than the substrate, and the adding of Mg and Sc elements can also raise corrosion resistance of Al alloy. |
