The analysis of defects in Tomography allows to characterize micro and macro defects within a component by means of a non-destructive approach.

Unlike traditional techniques used in metallography, CT technology allows to view the possible defects, locate their location, Evaluate the morphology of the defect and in addition support the metallurgist in understanding the mechanism of formation of the defect itself.

This type of defect analysis enables the three-dimensional viewing of a defect, thus enabling us to understand whether it is:

• Withdrawal porosity;
• Inclusion of gases;
• Internal stress cracking caused by cooling;
• inclusion of material not belonging to the analysed matrix;
• other type of defect

Conducted in parallel with destructive techniques, CT is a powerful diagnostic tool needed to pinpoint the defect and enable the technician to dissect the sample at the exact location.

The correct lay-out will allow a detailed and precise metallographic analysis. The products that are usually studied for this type of analysis are light alloy components (die-cast or gravity cast), plastic components (injected in a closed mold) or other types of material.
