Friction Stir Processing (FSP) is a novel solid state processing technique which can be used for microstructural modification of surface layers in metallic materials. This paper analyzes the effects of FSP process parameters on spindle torque acting on the tool and on the tool temperature. It has been shown that an increase in the rotational speed brings about a decrease in the torque and an increase of temperature. For temperature estimation in the stir zone a numerical model was applied, while for predicting a relationship between the spindle torque acting on the tool, rotational and travelling speeds and the down force, the artificial neural networks approach was employed. Light and electron (scanning and transmission) microscopy investigation showed that the FSP process reduces porosity and produces a more uniform distribution of second-phase particles.
