In the last few years materials with ultrafine-grained (UFG) structures having grain size in the range of nanometers or submicrometers have attracted considerable attention of researchers in various areas. However, there are still many open questions concerning the structure of UFG materials, because direct structural studies are difficult in the case of very fine grains. The behavior of submicrometer-grained materials is similar in many aspects to that of nanostructured materials. Due to the coarser grains they are more suitable for structural investigation. This paper deals with the annealing temperature dependence of the structure and room-temperature yield stress of submicrometer-grained copper.
