| Abstract: | Microstructure evolution of 5083 aluminum alloy during ultra-rapid annealing was studied by means of Gleeble-3500 thermal simulation system and electron backscatter diffraction (EBSD) technology. When the 5083 aluminum alloy with cold deformation of 80% was heated to 450 ℃ with heating rate of 500 ℃/s, the effect of annealing holding time (1-60 s, cooling rate of 40 ℃/s) on microstructure and mechanical properties was discussed. The results show that with the increase of annealing holding time from 1 s to 60 s, the average grain size of 5083 aluminum alloy increases from 4.94 μm to 6.44 μm, and the recrystallization textures in 5083 aluminum alloy consist of cube annealed texture of {001}<100>, rotation cube texture of {001}<110>, Gauss texture of {011}<100> and brass texture of {011}<211>. When the annealing holding time increases from 1 s to 60 s, on the whole, recrystallization textures in the alloy present a trend of increasing first and then decreasing, also the annealing holding time has little effect on strength of 5083 aluminum alloy, the yield strength and tensile strength of the 5083 aluminum alloy are about 170 MPa and 326 MPa, respectively. But the elongation of the 5083 aluminum alloy first increases from 25.63% to 30.06% and then decreases to 25.20%. |
