Abstract:

As an important type of Al alloys with excellent comprehensive properties, Al-Mg alloys with good corrosion resistance and weldability are widely used in aerospace, rail transit and marine ships. The recent research progress on the microstructure and property regulation of Al-Mg alloys during solidification, heat treatment and plastic deformation is summarized, and the characteristic of each regulation method is analyzed. The application of continuous rheo-extrusion forming technique in the fabrication of Al-Mg alloys is emphatically introduced, and the future development direction of Al-Mg alloys is prospected.
