The Al-Mg-Sc alloy sheets were prepared by semi-continuous casting、hot rollings cold rolling and stabilizing under the condition of industrialization production which dimension was thickness 2mm,by width 1200mm. Using thermal processing simulation and the research of plasticity、hardness measurement and electrical resistance test、tensile test at room temperature and metallographic analysis and electronic microscopy , the mechanical properties、corrosion resistance、microstructure and the variation discip...
