The Al-Mg-Sc alloys have many good properties such as low density, high strength, good ductility, excellent weldability and corrosion resistance, so more and more applications have been found in industries. Many Al-Mg-Sc alloys exhibit good superplasticity in a wide range of temperature and initial strain rate[1-3]. Their formability can be improved significantly in superplastic state. However......
