Abstract Ti-Cu-Mo laminated composites were fabricated through hot pressing and subsequent hot rolling by using Ti, Cu and Mo foils as raw materials. The effect of rolling behavior of Ti-Cu-Mo laminated composites and the rolling amount on the microstructure evolution of each layer were studied, and the influence mechanism of component layer and interface structure on the overall strength and plasticity of the composites was further revealed. The results show that hot rolling mainly results in refining and continuous hardening of Cu layers, but has limited influence on Ti and Mo layers in Ti-Cu-Mo laminated composites. The yield strength of the composites conforms to the rule of mixing, but it is also affected by the hardening and necking of the layer components. The Ti-Cu-Mo laminated composite achieves satisfied combination of yield strength (561 MPa) and plasticity (elongation is 7%) at a rolling deformation of 80%, mainly due to the sufficient hardening of Cu layers and the continuity maintaining of Mo layers.

Key words： Ti-Cu-Mo laminated composite hot rolling microstructure interface structure mechanical properties
