Fig. 8: Experimental setup including geometry of the coupons and the XCT scans.
From: Feature-based volumetric defect classification in metal additive manufacturing
Geometry and dimension of a as-built and b machined XCT coupon showing the scan volume of diameter and height of 1 mm. c Schematic illustration showing the XCT setup for Ti-6Al-4V coupons. Post-processing of XCT data: d volumetric scan image, e corresponding binary output, and f binary output excluding the high-density phase. The scale bars in (d–f) represent 200 µm. As a note, solid yellow and purple arrows point to a defect and a high-density phase, respectively. In addition, the dotted purple arrow signifies the removal of high-density phase from the analysis.
