Abstract

Abstract: Effect of different annealing temperature on the microstructure and properties of the actual pvoduction of 5AN6 aluminum alloy sheet was studied by means of mechanical properties test, optical microscope and corrosion property test. The results show that after annealing, the mechanical properties of the material continue to decline. After annealing at 280 ℃, the strength drops significantly. After annealing at 300-360 ℃, the mechanical properties tend to be stable. The grain structure in the original state is incomplete fiber structure, but the grain is obviously refined after annealing at 280 ℃. It can be considered that recrystallization occurs after annealing at 280 ℃. The temperature sensitive range of corrosion property of the 5AN6 alloy is 160-240 ℃, and the microstructure in this temperature range is continuous precipitation of β phase along the grain boundary.
