| Outline of Final Research Achievements |
The microstructure and aging behavior in Cu based age-hard enable alloys processed by high-pressure torsion (HPT) were systematically investigated. The effects of processing temperature on attainable maximum hardness by HPT and age-hardening behavior of the alloys after HPT were clearly explained. Moreover, the influence of natural aging on the artificial aging behavior of Cu-Be and Cu-T alloys systems were discussed. The obtained results in this study shed light on strengthening of the metallic materials by grain-refinement strengthening and precipitation hardening simultaneously.
