Material flow during Friction Stir Channeling (FSC) is responsible for the channel formation, which determines the thermo-hydraulic behaviour of channel. Earlier studies have investigated material flow during FSC using metallographic investigation that is destructive in nature and provides planar sectioned view only. In this experimental study X-Ray Micro Computer Tomography (CT) is used as non destructive and non invasive tool for material flow investigation during FSC. Micro CT is used to determine different flow zones responsible for formation of channel. Micro-CT analysis of broken pin embedded in the sample is done to determine material flow mechanism. The micro CT analysis is supported and validated by the metallographic investigation. Flow zones, mainly classified as shoulder influenced and pin influenced, are found to be responsible for formation of different regions of channel. Development of proper insight about material flow during FSC may lead to formation of channels with controlled and uniform geometry.
