X-ray tomography for 3D non-destructive imaging has been widely adopted and operated under two primary contrast mechanisms : X-ray absorption and phase contrast. Both rely on material density differences to absorbed X-rays and provide contrast.
However, single-phase polycrystalline materials (e.g., steels, alloys, ceramics) do not exhibit any absorption contrast that reveals the underlying grain microstructure. Synchrotron-based X-ray imaging methods (such as diffraction contrast tomography (DCT)) provide crystallographic information from the diffraction signals of single-phase polycrystalline samples, non-destructively and in three dimensions (3D).
Now, advancing laboratory X-ray microscopy (XRM) one step further, non-destructive 3D grain mapping is accessible in your home laboratory, enabled by lab-based diffraction contrast tomography available on ZEISS Xradia 620 Versa and ZEISS Xradia CrystalCT.
Today we will present to you in this web seminar the latest capabilities of laboratory-based DCT, including the recently introduced advanced diffraction scanning modes that address the challenge of achieving true sample representivity by seamlessly imaging massive volumes of samples at an unprecedented scale.
We will share application use cases of large volume grain mapping on a wide variety of materials ranging from metals, ceramics and geomaterials, with further discussions on how this unique laboratory X-ray imaging capability can solve your research problems.
