Influence of impurities and deformation temperature on the saturation microstructure and ductility of HPT-deformed nickel

Ni with different purities between 99.69 and 99.99 wt.% was deformed by high-pressure torsion (HPT) to high strains, where no further refinement of the microstructure is observed. The HPT deformation temperature varied between −196 and 400 °C. Both impurities and temperature significantly affect the...
