Porosity -------- N2-1, Ar-1, Ar-2, and Ar-3 are CT datasets of a few different gas atomized 17-4 stainless powders. They have various levels of entrapped gas porosity which were intentionally introduced during atomization. .. image:: ../img/tomo_00090.png :width: 512pt :height: 512pt Detailed information area available at :cite:`Wu:2021`. +---------------------------------+------------------------------------+ | Instrument | APS 2-BM-A fast tomo | +---------------------------------+------------------------------------+ | Energy | pink beam | +---------------------------------+------------------------------------+ | Scan Range | 180 degree | +---------------------------------+------------------------------------+ | Number of Projections | 1500 | +---------------------------------+------------------------------------+ | White Fields | 10 before | +---------------------------------+------------------------------------+ | Dark Fields | 10 before | +---------------------------------+------------------------------------+ | Mode | fly-scan | +---------------------------------+------------------------------------+ | Detector Name | FLIR | +---------------------------------+------------------------------------+ | Exposure Time | 0.024 s | +---------------------------------+------------------------------------+ | Pixel Size | 0.69 µm | +---------------------------------+------------------------------------+ | Detector shutter mode | global | +---------------------------------+------------------------------------+ | Detector Dimension (mm) | 1.55 | +---------------------------------+------------------------------------+ | Detector Dimension (mm) | 1.41 | +---------------------------------+------------------------------------+ | Objective Magnification | Mitutoyo 5x | +---------------------------------+------------------------------------+ | Scintillator | LuAG 10 µm | +---------------------------------+------------------------------------+ To load the data sets and perform a basic reconstruction using `tomopy `_ :: tomopy recon --file-name tomo_00090.h5 tomopy recon --file-name tomo_00091.h5 tomopy recon --file-name tomo_00092.h5 tomopy recon --file-name tomo_00093.h5 .. _tomo_00090: https://app.globus.org/file-manager?origin_id=9f00a780-4aee-42a7-b7f4-6a2773c8da30&origin_path=%2Ftomo_00090_to_00093%2F .. _tomo_00091: https://app.globus.org/file-manager?origin_id=9f00a780-4aee-42a7-b7f4-6a2773c8da30&origin_path=%2Ftomo_00090_to_00093%2F .. _tomo_00092: https://app.globus.org/file-manager?origin_id=9f00a780-4aee-42a7-b7f4-6a2773c8da30&origin_path=%2Ftomo_00090_to_00093%2F .. _tomo_00093: https://app.globus.org/file-manager?origin_id=9f00a780-4aee-42a7-b7f4-6a2773c8da30&origin_path=%2Ftomo_00090_to_00093%2F +-------------+-----------------------------------------+-----------------------------------------+ | Tomo ID | Original File Name | Sample Name used in :cite:`Wu:2021` | +-------------+-----------------------------------------+-----------------------------------------+ | tomo_00090_ | 070_carpenter_174ph_powder_27347 | Ar-3 | +-------------+-----------------------------------------+-----------------------------------------+ | tomo_00091_ | 072_carpenter_174ph_powder_017175 | Ar-2 | +-------------+-----------------------------------------+-----------------------------------------+ | tomo_00092_ | 073_carpenter_174ph_powder_Y5863B | N2-1 | +-------------+-----------------------------------------+-----------------------------------------+ | tomo_00093_ | 074_carpenter_174ph_powder_017174 | Ar-1 | +-------------+-----------------------------------------+-----------------------------------------+
