Hydrostatic extrusion is a technique based on severe plastic deformation. Characteristic features of this process are very large deformation, high strains, strain rates and considerable thermal effect. Temperature is one of the most important factors which controls the structure and mechanical properties of material during this process. Due to very high extrusion pressure (of the order of magnitude 1 GPa) and high speed of extruded material only the ‘contactless’ methods of the product temperature measurement during the process are possible. Results of measurements with use of ThermaCAM SC 2000 at recording frequency 50 Hz are presented in the paper for hydrostatic extrusion of aluminium wires with OD between 2-3 mm.
