Effect of X-ray Computed Tomography Magnification on Porosity Analysis of Additively Manufactured Parts
X-ray computed tomography has been widely used for inspection of parts manufactured using additive manufacturing(AM)and powder metallurgy(PM).The ability of this method to non-destructively evaluate the porosity content of parts fabricated using AM and PM has made it a reliable method for such inspection.The results obtained from this method are highly dependent on CT acquisition parameters such as the magnification(resolution)at which the part has been scanned.Depending on the size of the parts the scan might need to be performed at lower magnifications which results in loss of information for porosity analysis.Therefore the effect of changing CT magnification on the obtained porosity of an additively manufactured specimen made of AlSi10Mg is investigated in this study.The specimen was scanned at various magnifications resulting in data sets with different resolutions.The porosity content was measured for each data set and the results showed that the porosity measurement using CT is highly dependent on the magnification(resolution)at which the data sets are acquired.The results from this study provided essential information about the porosity content which should be expected depending on the CT magnification.
