AB  - Effects of different annealing processes on the mechanical properties and interfacial microstructure of warmrolled Ti/Al/Al/Fe laminated multimetallic composite plates (LMCs) are investigated in this manuscript. The results indicate that with the increase of annealing temperature, the thickness of the interface diffusion layer gradually increases, the bonding strength of Ti/Al interface gradually increases, while the tensile shear strength of Fe/Al interface first decreases and then increases. When annealing at 550 ℃/1 h, Ti/Al/Al/Fe composite plates exhibit the best comprehensive properties, tensile strength (170 MPa) and elongation after break (52%). After annealing, TiAl3 phase is formed at the Ti/Al interface, while FeAl3, Fe2Al5, and Fe4Al13 phases are formed at the Fe/Al interface. The interface gradually transitions from mechanical meshing to large-area metallurgical bonding.
