Diffraction Contrast Tomography for 3D Materials Science Now in the Scientist’s Lab

News

The development of new materials needed in frontiering fields such as metals for additive manufacturing, alloys for bioengineering, or the high-strength-to-weight materials required by aerospace and automotive industries, requires the use of an expanding set of new research techniques. Unlocking crystallographic information used for new materials development, ZEISS now takes diffraction contrast tomography out of the exclusive realm of the synchrotron and extends it right into the researcher’s laboratory with the LabDCT advanced imaging module.

LabDCT non-destructively obtains 3D crystallographic information from polycrystalline samples, enabling a handshake between theoretical and practical worlds for predictive materials design. Combining grain orientation information with microstructural features such as cracks, porosity, and inclusions opens new possibilities for characterizing damage, deformation and growth phenomena in 3D materials science. Imaging these microscopic features in three dimensions with advanced contrast techniques enhances the exploration potential and collective understanding of fundamental materials mechanisms behind these phenomena.

LabDCT extends the ability of 4D and in situ microstructure evolution studies to explore the influence of crystallography on materials systems. Philip Withers, Professor of Engineering Materials, University of Manchester and Director of the BP International Centre for Advanced Materials, noted, “LabDCT represents a major step towards addressing the grand multi-scale challenge in 3D materials science. By providing non-destructive 3D information about the grain orientations and morphologies, LabDCT promises to deepen our understanding of microstructure-property relationships and accelerate the development of micromechanical models for a variety of materials degradation and deformation processes.”

LabDCT is immediately available as an optional module for the ZEISS Xradia 520 Versa 3D X-ray microscope. LabDCT includes GrainMapper3D analysis software developed by Xnovo Technology ApS.
