Figure 1
Methodology schematic and detailed structure of a RAM highlighting useful qualities. X-ray projection image of (a) abrasive paper, (b) steel wool and (c) Al–Cu alloy; the scale bars of these images are 1.0 mm long. Some pores are marked with yellow arrows in the speckle image (c). (d) Schematic representation of the experiment setup (not to scale). For each projection a stack of speckle images was recorded using an X-ray detector by scanning alloy transversely (along the x direction) to the X-ray beam. (e) Volume rendering of an X-ray tomographic image of the Al–Cu alloy (the black colour represents gas porosity), (f) porosity in the alloy. Here, the size of the tomographic image is 1695 µm × 918 µm × 2124 µm.
