【 摘 要 】

Cu-Cr-Zr alloy belongs to precipitation-enhanced, high-strength and high-conductivity copper alloys. The volume fraction of specimen deformation was 25% and the deformation rates were 0.01∼1s-1 with the deformation temperature ranged from 500°C to 800 °C at Gleeble-1500 thermal simulator. The results state that the rheological stress of Cu-Cr-Zr alloy decreases with a rising temperature at a same deformation quantity. Along with the increasement of the strain rates and the temperatures during hot deformation, the grains of Cu-Cr-Zr alloy were elongated perpendicularly to the direction of compression. When the deformation temperature was 600 °C, some of fine recrystallized grains appeared.
