Although high-pressure torsion (HPT) is now a well-established technique for imposing severe plastic deformation on metallic materials, the technique is generally restricted to use with thin disk samples. This paper describes experiments which were conducted to evaluate the potential for making use of HPT with bulk samples in the form of small cylinders. The experiments were performed using an Al-Mg-Sc alloy and the samples were strained under a pressure of 1 GPa at room temperature. The results demonstrate excellent microstructural refinement in the vicinity of the central zone around the periphery of the cylinders.
