Ultrafine-grained (UFG) pure Cu exhibits softening compared to coarse-grained (CG) Cu in the steady state of deformation at elevated homologous temperatures below 0.31, while commercially pure UFG Ti does not. The softening of UFG Cu can be explained by the fact that the spacing d 0 of high-angle gr

## Abstract The mechanical behavior of the Tiโ6Alโ4V ELI alloy in both conventional grain size (CG) and ultrafineโgrained (UFG) conditions under tension and compression at elevated temperatures (500โ800โยฐC) is considered. Grain refinement by equalโchannel angular pressing (ECAP) followed by multicy
Compression tests were performed on the well-annealed coarse grained (CG) and the near dislocation-free ultrafine grained (UFG) 5083 Al alloys at 298 K and 77 K. The mechanical behavior of the CG alloy was dominated by the stage III hardening at 298 K and the stage II hardening at 77 K. The microstr
