Pore structures of additively manufactured metal parts were investigated with X-ray
Computed Tomography (XCT). Disks made of a cobalt-chrome alloy were produced using …

X-ray tomography has emerged as a uniquely powerful and non-destructive tool to analyze
defects in additive manufacturing. Defects include unintended porosity, rough surfaces and …

The deployment of additive manufacturing processes relies on part quality, specifically the
absence of internal defects. Some of those defects have been associated with porosities in …

X-ray computed tomography (XCT) is widely used in additive manufacturing (AM) to obtain
discrete analysis of internal material discontinuities, especially the porosity of AM …

The objective of this work is to model and quantify the layer-wise spatial evolution of porosity
in parts made using Additive Manufacturing (AM) processes. This is an important research …

Porosity is a major issue in solidification processing of metallic materials. In this work, wedge
die casting experiments were designed to investigate the effect of cooling rate on …

Quality control in metal additive manufacturing prioritizes the development of advanced
inspection schemes to characterize the defect evolution during processing and post …

If additively manufactured metal parts are to be used as performance critical components in
the aerospace and other high-value industries, then non-destructive methods for measuring …

Micro computed tomography (microCT) allows non-destructive insights into the quality of
additively manufactured parts and the processes that produce them. MicroCT has been used …

In this paper the application of X-ray microCT to the non-destructive testing of an additive
manufactured titanium alloy component of complex geometry is demonstrated. Additive …
