An experimental investigation and modelling of Friction Stir Processing

In this paper experimental and numerical modelling of the Friction Stir Processing technique are presented. The experiments were carried out on cast aluminium alloy AlSi9Mg. A conventional tool without a pin was used. During the trials, the tool temperature, torque and forces acting on the tool were measured. The results revealed that an increase in the rotational speed caused an increase in the temperature and a decrease in the torque. Furthermore, the increase in travelling speed caused a decrease in the tool temperature and an increase in the torque. The experimental results were compared with that achieved based on the numerical modelling.
