Evaluation of porosity in silumin alloy castings by X-ray tomography
https://doi.org/10.22349/1994-6716-2024-120-4-174-184
Abstract
The article presents information on the study of porosity of control samples cast from silumin alloy using X-ray computed tomography (CT). The theoretical calculations and experiments had a goal: to develop an X-ray tomographic scale of gas porosity that would be absolutely adequate to the results of metallography. Currently, a radiographic porosity scale is widely used by the operator who compares the sample radiograph with a radiograph of the test object. Such an assessment of the quality of non-destructive testing is subjective, and it is determined by the experience, physical health of the operator performing the control, and the quality of radiographic images. X-ray tomography of reference porosity samples provides quantitative indicators of porosity and completely eliminates the subjective factor.
