For TA1 titanium alloy and 5A06 aluminum alloy experimental plates, the hot-melt drill riveting technology was used to connect them, and the static behavior and failure mechanism of the joints were researched systematically by static tensile test and scanning electron microscope test. The results show that when the aluminum plate is placed below for riveting, it is more conducive to form a long and thick bushing and the forming quality is better, and when the titanium plate is placed on top for riveting, the meshing degree of the thread between the plate and the rivet is lower. The FTT joint has the best mechanical properties and the highest buffering and shock-absorbing properties, and the mechanical properties of FAT joints are much higher than those of FTA joints. When the aluminum plate is the lower plate, the failure mode is typical ductile fracture characteristics, and when the aluminum plate is the upper plate, the failure mode shows brittle fracture characteristics. The fracture of the titanium plate shows a mixed fracture form of shear fracture and ductile fracture. The rivet head of the FAA joints is almost undamaged, and the rivet head of the FTT joints is severely damaged.
