The Effect of Predeformation on Creep Strength of 9% Cr Steel. [PDF]

open access: yesMaterials (Basel), 2020
Martensitic creep-resistant P92 steel was deformed by different methods of severe plastic deformation such as rotation swaging, high-pressure sliding, and high-pressure torsion at room temperature. These methods imposed significantly different equivalent plastic strains of about 1–30. It was found that rotation swaging led to formation of heterogeneous
