Resum
Several authors have noticed that relatively pure coppers with different oxygen levels present a higher hot flow stress as the oxygen content increases. This work attempts to demonstrate that a large contribution to the observed increase of stress is due to precipitation of fine Cu2O particles during hot working. Three fire-refined 99.9% pure coppers with different oxygen levels (26 ppm, 46 ppm, and 62 ppm) were hot compressed at temperatures 600–950 °C and at a strain rate range 0.001–0.3 ...
