| Abstract | Microindentation creep tests on an electrodeposited extremely fine (4.9 nm) nanograined (ng) Ni-14.2 at.% Mo (Ni-14.2Mo) at both room temperature (RT) and liquid nitrogen temperature (LNT) demonstrated that lowering temperature retarded softening in the ng Ni-Mo alloy. The obtained strain rate sensitivity at LNT was one order of magnitude lower than that at RT. Microstructural characterization revealed that mechanically-driven grain boundary (GB) migration was greatly suppressed by lowering temperature, which might be ascribed to the presence of solute Mo atoms that significantly retarded coupled GB motion at LNT. Deformation was instead carried by shear bands. (C) 2020 Published by Elsevier Ltd on behalf of The editorial office of Journal of Materials Science & Technology. |
