Composite Architecture. Three-dimensional X-ray computed tomographic reconstructions of W-Cu composites. (a–c) Show the Cu (a) and W (b) phases of an anisotropic lamellar composite produced by freeze-casting and reduction of a WO3 precursor, sintering and Cu infiltration; the volume fraction of W is 57% W/Cu. Panels (d–f) show the different phases of an isotropic W-Cu composite (65 vol.% W) produced by partial sintering of W powders followed by Cu infiltration. For both reconstructions the voxel size is 1.3 μm.
