Grain boundary fracture was studied in tensile test for peak-aged balanced and excess Si Al–Mg<sub>2</sub>Si alloys. The route of crack propagation for intergranular fracture in these alloys was considered by Schmid factor (S.F.) and stress transmission factor (<i>N</i><sub>ij</sub>) by crystal orientation to tensile axis. The texture of these alloys before tensile test was recrystallized textures, and there were no significant difference of initial texture between these alloys. Fractured grain boundaries has been classified into the following four groups:<br>· Group A: Larger difference in S.F. than 0.05 and higher <i>N</i><sub>ij</sub> than 0.5.<br>· Group B: Larger difference in S.F. than 0.05 and lower <i>N</i><sub>ij</sub> than 0.5.<br>· Group C: Smaller difference in S.F. than 0.05 and higher <i>N</i><sub>ij</sub>. than 0.5.<br>· Group D: Smaller difference in S.F. than 0.05 and lower <i>N</i><sub>ij</sub> than 0.5.<br>The cracking was influenced by the grain boundary with larger difference in S.F. and lower N<sub>ij</sub> in the balanced alloy. The propagation of cracks was influenced by grain boundaries of group B, C, or D with the angles from 60° to 90° to the tensile axis. The cracking and propagation of cracks occurred all together in excess Si alloy at the same time as beginning of tensile test, and grain boundaries in this alloy mostly fractured in the group D with the angle of 30°–90° to the tensile axis.
