The use of nano-computed tomography (nano-CT) in non-destructive testing of metallic parts made by laser powder-bed fusion additive manufacturing

Computed tomography (CT) magnifies the spectrum of measurable internal features with minimal preparation and exceptional resolution. In this study, non-destructive nano-scale and micro-scale CT examinations of aluminum-based part manufactured by laser powder-bed fusion additive manufacturing (LPBF-A...

Description
Summary:Computed tomography (CT) magnifies the spectrum of measurable internal features with minimal preparation and exceptional resolution. In this study, non-destructive nano-scale and micro-scale CT examinations of aluminum-based part manufactured by laser powder-bed fusion additive manufacturing (LPBF-AM) are compared to determine the extent of defect details (size and distribution of defects/pores) not detectable with micro-CT. Our findings show nano-CT system is able to provide insightful information for effective characterization of AM-made parts to predict their strength/durability more reliably. Graphical abstract ᅟ
