An innovative twin-roll casting process that produces the comprehensive effect of “energy field agitation + dendrite breaking + asymmetric rolling” by vibration of the roller was used for preparation of Ti/Al composite sheets. The increase of meshing layer thickness from 3.1 μm to 4.5 μm under the effect of vibration of the roller enhances the bonding strength from 14.9 N/mm to 27.0 N/mm. The increase of intermetallic layer thickness from 4.5 μm to 7.75 μm under the effect of “vibration twin-roll casting + annealing” enhances the bonding strength from 27.0 N/mm to 34.0 N/mm, and annealing transforms the mechanical meshing “direct bonding” of the “two phases” into the intermetallic layer “transition bonding” of the “three phases,” which realizes the transformation of laminated metal composite mode, and the composite mode is based on the bonding of the intermetallic compound layers with reticulation connection structure that is stronger than mechanical engagement.
