Factors Influencing the Shearing Patterns in High-Pressure Torsion

Abstract:

High-pressure torsion (HPT) is a processing technique in which samples are subjected to a high pressure and torsional straining. Experiments show that the shearing patterns in HPT are dependent upon the alignment of the anvils within the HPT facility. Using a two-phase duplex stainless steel as a model material, experiments were conducted by placing the anvils in different amounts of initial misalignment. The results demonstrate the importance of always ensuring that the upper and lower anvils are in good alignment prior to HPT processing.
