Positron emission particle tracking (PEPT) has been demonstrated to be a valuable research tool for the tracking of inclusion movement in liquid metals. It could therefore be used to test inclusion removal strategies in castings, such as the efficiency of filters, and to validate and benchmark inclusion models in casting simulation software. Research has only just begun on the application of this technique to the casting process, and further developments are aimed at reducing the size of the particle used, to bring the radioactive particles closer to the size of inclusions in castings, and increasing their radioactivity to improve the accuracy of their detection.
