Examining the inside of a material is often a destructive process that risks obscuring or deforming critical details. However, advances in computed tomography have opened new opportunities to obtain high resolution, three-dimensional reconstructions of materials in a non-destructive manner. Through this technique materials scientists can now identify cracks and voids in materials without the need for mounting and polishing, observe processes like battery degradation and dendrite growth in real time, and even obtain 3D diffraction data for identifying phase distributions in a material. In covering this fascinating topic, we are joined by William Harris from Zeiss Microscopy who shares his expertise as he walks us through the many ways computed tomography is reshaping materials science.
