Edge crack is a common defect in the rolled magnesium alloy sheet which increase the rolling cost. In this study, the effect of tension on the edge crack of AZ31B sheet rolled with on-line heating rolling was investigated. The sheets were rolled under different tension at the rolling temperature of 523 K with thickness reduced from 1 mm to 0.6 mm in 1 single pass. The microstructures, texture, and mechanical properties, fracture surfaces of the sheets were characterized. The results show that the number of edge crack and crack depth increase with the increase of the tension. EBSD results show the crack tip area are mainly composed of fine recrystallized grains.
