Experimental Results and Analysis of 5052 Aluminum Alloy
1 Effect of intermediate annealing on the grain structure of 5052 aluminum alloy The grain structure of the longitudinal section of the cold-rolled plate to 1.8mm thickness and the recrystallization annealed plate at 350°C×3h after cold rolling is shown in Figure 1. The grain size distribution of the plate after recrystallization annealing is shown in Fig. 2 .
