Abstract: | This paper investigates the effects of process annealing on the mechanical properties of strain hardened copper from Kabel Metal Nigeria Limited. The results obtained showed that hardness of copper during cold rolling increases with degree of deformation due to strain hardening. The maximum value of hardness obtained was 117 HB at 40% reduction in area, while the average hardness values obtained after annealing temperatures of 3000C, 4000C and 5000C were 79.2, 67.2 and 45.7 HB respectively. During tensile test, the cold-rolled copper fractured with very little elongation. The maximum ultimate tensile stress obtained was 188.4 N/mm2 at 20% reduction in area. Anneal strengthening effect which increases with increasing degree of prior cold work was observed in the copper |
