WORK SOFTENING BEHAVIOUR IN COLD DRAWN OXYGEN FREE HIGH CONDUCTIVITY COPPER FOR FUSION REACTOR USE
Tensile tests were carried out on cold drawn oxygen- free high conductivity copper in the temperature range of 20-450 deg. C in order to generate strength data for fusion technology applications. The rate of decrease in the yield as well as in the ultimate stress, with increasing temperature, showed a large increase in the temperature range of 250 to 350 deg. C. This is ascribed to work softening which is associated with progressive recrystallization concurrent with deformation. The microstructure of the samples deformed at 400 deg. C was found to be completely recrystallised and the fracture mode was found to be ductile over the entire range of test temperatures.
