New publication: CT based procedure for reproducible porosity measurement
Metallic parts made by selective laser melting technology or other techniques are frequently evaluated for their internal porosity. The non-standardized pores segmentation is one of the key aspects to apply in order to achieve a precise porosity measurement using X-ray computed micro tomography. In our new article, we presented a new porosity analysis procedure which is based on the global thresholding and the correlation with metallographic image data. The procedure is independent on the obtained voxel resolution and makes an analysis reproducible. The novelty of this work is that the computed tomography is used for a comparative porosity analysis of samples from separate measurements.
