Recrystallization and texture evolution in friction stir welded 7050-T7451 aluminum alloy
Friction stir welding was performed on 7050-T7451 alloy of the Al-Zn-Mg-Cu system. Sound welds without defects were produced using a rotation rate of 600 rpm and a traverse speed of 100 mm/min. The as-received base material (BM) displayed overaged microstructures with coarse, elongated grains and fine, partially recrys...
