Abstract The Ti/Al/Ti clad plates exhibit a broad spectrum of potential applications. However, the conventional techniques of hotpressing composite and explosive composite are intricate and environmentally hazardous. A novel method was introduced for preparing clad plates, namely, the powder-in-tube method. This method involves a combination of cold rolling, annealing at a temperature of 550 °C, and double rolling. The morphology of the intermetallic compound layer was analyzed through the utilization of interface stripping test, tensile test, and microscopic characterization. The interface morphology, interface bonding properties, tensile fracture structures, and properties of plates under the first and second rolling were compared, along with the effects of intermetallic compounds on the interface properties. The results indicate that the powder-in-tube method, when annealed at 550 °C, can produce a composite plate featuring a complete and uniform Ti/Al interface. The obtained plate exhibits a peeling strength of 21.5 N/mm, tensile strength of 424 MPa, and elongation of 11.5%. Furthermore, a systematic analysis was conducted to determine the causes of performance degradation observed during annealing at temperatures of 600 and 650 °C.
