In this paper experimental and numerical modelling of the Friction Stir Processing tech-
nique 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 rota-
tional 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.
