The effect of the low angle grain boundary structure on the mechanical properties and deformation behavior was investigated using Mg‐Al‐Zn alloys, which were produced by caliber rolling. The {10–12} deformation twins were formed at the head of the crack‐tip during fracture toughness even in the fine‐grained structures; however, the present caliber rolled alloys showed high strength and fracture toughness balance that resulted from the high fraction of low‐angle grain boundaries, which did not become the origin of the micro‐void formation.
