Application of X-ray computed tomography to compare gravity casting to counter-gravity low-pressure air-melted process

The purpose of this paper is to evaluate the internal structure of alloys similar to AlSi9Mg (EN AC-43300), made with the counter-gravity low-pressure air-melted process (CLA) and with the gravity casting process. The X-ray computed tomography (CT...
