This study aimed to investigate the effects of grain refinement on forming and brazing characteristics of three-layer 4343/3003/4343 aluminum clad sheets. The clad sheets with 0.7 mm thickness were fabricated by hot roll bonding process. Al-10Ti master alloy was used for grain refining of 3003 Al-Mn core alloy. The Ti inoculation level was changed up to 0.1%. The forming characteristic of the clad sheets was strongly dependent on the recrystallization microstructure feature according to Ti inoculation level and stress relief annealing condition. 0.011Â¼0.1%Ti inoculation treatment significantly improved the biaxial formability of the clad sheets at room temperature by 2 times...
