To improve the properties of castings a new technique to observe fluid flow and study the motion of oxygen-bearing inclusions has been developed. The new technique, Positron Emission Particle Tracking (PEPT), enables a single radioactive tracer particle moving inside a liquid metal casting to be tracked with an accuracy of some millimeters, which depends on the liquid metal and mould material properties. These novel experiments give promising results to observe the liquid metal flow and locate the tracked particle in the cast metal. Experiments have shown that various particle sizes can be used to observe the liquid metal flow if the particle has sufficiently initial radioactivity. The different types of particles are considered and the radioactivity of them is compared in terms of usability for the tracking in the aluminium fluid flow.
