3D Elemental Mapping by K Edge Subtraction Imaging in an Al-Zn-Ca-Ti Alloy

Abstract

Method: Microtomography, characteristics: 3D visualization of alloying elements by dual energy subtraction imaging at the zinc K edge, conditions: A monochromatic X-ray was used at BL20XU of SPring-8 for the tomographic experiment. Isotropic voxel with a 0.474 pm edge was achieved. The material used was the cell wall of an aluminum alloy foam.
