This paper studies the effect of annealing on the microstructure and hardness, microhardness and electrical conductivity changes of cold deformed (ε=40%) sintered pure copper and Cu-4at.% Au alloy. The samples of pure copper and Cu-4at.%Au alloy were obtained by sintering, followed by prefinal rolling, quenching and final rolling with 40% reduction. Isochronal annealing was performed from 60oC to 700oC. The sintered Cu-4at.%Au alloy has made a two-step increase in
hardness, microhardness and electrical conductivity due to anneal hardening effect. The correlation between the microstructural changes and changes in properties was established.
