dc.description.abstract | The wear property of NiTi is one of the most important properties of this alloy. In the current study, the effect of high-pressure torsion (HPT) process on the wear properties of an austenitic NiTi shape memory alloy is investigated. Full density NiTi samples with a composition of Ti-56 wt% Ni are fabricated using hot isostatic pressing (HIP), followed by the HPT process at room temperature, with an applied pressure of 6 GPa for 10 turns. The microstructural analysis reveals that the HIP-processed samples with a B2-NiTi phase evolve into significant grain refinement after HPT process and an interwoven B2-B19' nanocrystalline/amorphous structure formed, leading to increased hardness in these samples. The results of the wear tests using a ball-on-disc configuration at room temperature demonstrate that the wear performance of the samples is improved after the HPT process. This is due to greater hardness and better pseudo-elasticity in the HPT-processed samples. | - |
