High Pressure Torsion (HPT) is a widespread processing technique in the Severe Plastic Deformation (SPD) community with some unsurpassable advantages compared to other SPD-techniques with regard to the applicable pressures and strains. These two factors have allowed the successful processing of a wide range of materials ranging from metals and alloys in bulk and powder form to rather exotic examples such as ceramics. The drawback of the generally small sample diameters and thickness strongly restricts possible application fields. To overcome these restrictions novel HPT setups have been designed in recent years. In this contribution the current technical limits in HPT processing regarding sample size and homogeneity will be reviewed and underlined with experimental results using different HPT tools allowing sample diameters up to about 100 mm.
