| Abstract |
The high-temperature mechanical behaviour of copper polycrystals was examined using stress relaxation tests in conjunction with microstructural observations on deformed and quenched specimens using transmission electron microscopy. The relationship between the dynamic recrystallization subsructures and the flow behaviour was analysed in detail, and the mechanisms of dynamic recrystallization were also discussed. Nucleation of dynamic recrystallization is attributed to deformation-induced instabilities of the dislocation structure. The formation of dislocation cells and subgrain structures is of great significance to the understanding of high-temperature deformation. |
