Notes:
Al-Zn-Mg-Cu alloy containing 2%Mn was made using spray forming method and hotextrusion. XRD, OM, and SEM were used to investigate the microstructure. Results showed that afterbeing hot extruded and solid solution treated, the Al alloy matrix had uniformly fine recrystallizedgrain with an average size of 8μm. The particles of MnAl6 were formed during the spray formingprocess and distributed along the grain boundary. Deformation and spheroidization of MnAl6particles were occurred during post hot extrusion and solid solution treament, which would be benefitto the improvement of toughness of Al alloy. When aged at the T6 conditions, the tensile strength ofthe Al alloy was increased up to 775MPa with the elongation of 4.3%, the fracture surface consistedmainly of dimples with a size lower than 500nm
