Abstract:
A better fundamental understanding of the sintering process requires experimental data describing in 3D particle rearrangement processes, especially particle rotations. Therefore, synchrotron computed tomography (SCT) is used to investigate the particle rearrangements during sintering. The specimens consisting of spherical monocrystalline copper powder were measured in a special in-situ furnace. The data is analyzed by a custom image analyzing software based on photogrammetric methods to determine the coordination, the centre approach and rotation of each particle in a 3D specimen. The sintering of monocrystalline copper spheres analyzed using SCT is compared to literature data of different test arrangements and dimensions.
