Abstract
The effect of second phase particles on the bendability of Al–Mg–Si alloy for outer panels in autobodies was investigated by changing solution heat treatment condition and quenching rate. Slow quenching rate made inferior bendability. Because the number of second phase particles on the grain boundaries increased. Crack by bending test was not observed with short solution heat treatment time. However, in the case of long solution heat treatment time, the crack was observed. Depth of the crack increased with solution heat treatment time to maximum value and then decreased. The number of second phase particles decreased and the formation of shear bands by deformation increased with solution heat treatment time. When the formation of shear bands is observed significantly and the number of second phase particles is many, the crack occurs easily along the shear bands and the second phase particles.
