Microstructural evolution and phase stability of Cu/Nb nanolaminates subjected to severe plastic deformation by high pressure torsion

Ekiz, Hayriye ElvanUniversity of Illinois at Urbana-Champaign2015

… was applied in a controlled way using high pressure torsion, reaching very large strains, allowing to investigate microstructural evolutions and phase stability as a function to strain, and to reach true steady states. The results show that the two dimensional layered microstructure was …
