This study addresses the urgent problem of developing high-performance metal-based conductor materials capable of adapting to complex working environments. A novel method, called Accumulative Hot Pressing Roll Bonding (AHRB), is proposed for fabricating Cu/Mo/NGs multilayer composite materials. Through repetitive cold rolling and hot-pressing operations, nanoscale metal-based layered materials with thicknesses in the range of hundreds of nanometers are successfully obtained. This material features a multilayered interconnected net structure with Mo2C as the core and CuMo alloy as the framework. The layers are dislocated and connected to each other. The mechanical properties of the materials are significantly improved due to heterogeneous strengthening and grain refinement. The material achieves a tensile strength of 854 MPa, while the conductivity remains stable between 55% ∼ 60% IACS. The reaction between NGs and Mo leads to the formation of an Mo2C interface, while the hot-pressing operation promotes the formation of a CuMo diffusion interface. These two interfaces enhance the interlayer forces of the composites, thereby improving the material's integrity. The investigation of Cu/Mo/NGs multilayer composite materials presents a novel approach for alloying refractory metals Mo and Cu, offering promising prospects for future engineering applications.
