The microstructure and mechanical properties of 1060Al/TA2/CCSB explosive composite plate binding interface at different annealing temperatures were studied. The results show that the composite plate exhibits a continuous and uniform distribution of waves at its binding interface, there are swirls, melting blocks, surface microcracks and ability shear strips other defects. Take a test, cutting test, and microhardness testing on the composite plate, pulling breakage occurs at the 1060Al/TA2 interface, the shear strength and the microhardness of the 1060Al/TA2 interface are lower than the TA2/CCSB interface, and the binding interface is severe Plastic deformation, resulting in processing hardening and grain refinement of the composite plate interface, and the hardness value at the interface is highest and along the boundary to the matrix gradient distribution. The existence of a composite palette hinders the necklace process during the stretching process, and the composite plate is improved. As the annealing temperature rose to 400℃, the combined interface responded, the processing hardening effect was eliminated, so that the interface hardness was lowered; the ASB disappeared and converted into an equal shaft alpha grain, defect decreased; the melting block at the interface was dissolved, so that the composite The binding interface of microstructure is more uniform and good comprehensive performance is obtained.
