摘要：
Microstructures and failure mechanisms of spot friction welds in aluminum 6061-T6 lap-shear specimens are investigated based on experimental observations. Different processing parameters were used to join the aluminum sheets. Optical micrographs of the cross sections of spot friction welds in lap-shear specimens before and after failure are examined. These spot friction welds show the failure mode of nugget pullout under lap-shear loading conditions. The experimental observations suggest that under lap-shear loading conditions, the failure is initiated near the stir zone in the middle part of the nugget and the failure propagates along the circumference of the nugget to final fracture.
