Abstract: Effect of cold deformation on grain size, mechanical properties and earing rate of 5052 aluminum alloy sheet was studied by metallographic microscope, tensile testing machine and earing rate tester. The results show that the yield strength of the 5052 aluminum alloy cold-rolled sheet has a linear relationship with the cold deformation rate. The change of tensile strength and yield strength caused by 10% deformation is about 20 MPa and 15 MPa, respectively. After recrystallization annealing, the grain size of the annealed sheet has a linear relationship with the cold deformation rate and yield strength. When the cold deformation rate is 50%-60%, the earing rate and plane anisotropy index Δr of the annealed sheet is smaller.
