摘要	Hierarchical 3D interpenetrating-phase structures, commonly found in natural biological materials, are effective in enhancing the damage tolerance of materials; nevertheless, constructing such structures in engineering metallic materials remains a big challenge. Here, we report the fabrication of a hierarchically structured W-Cu composite by reactive melt infiltration technique via dissolving Fe atoms from a precursor W-Fe alloy with Cu melt. The W and Cu phases exhibit multimodal distributions of characteristic dimensions, ranging from sub- micron to over 20 micrometers, and are mutually interpenetrated at different dimensional levels within the composite. Such structure endows the composite with high compressive strengths at both room and elevated temperatures that surpass those of previously reported W-Cu composites, making it appealing for electrical and thermal structural applications. The reactive melt infiltration technique also holds promise for developing new high-performance metal composites with hierarchical 3D interpenetrating-phase structures.
