The densification of porous copper strips obtained from the combined reduction and sintering of cuprous oxide preforms by cold rolling has been discussed. It has been shown that such strips, although containing a relatively large amount of porosity, exhibit no problems during cold rolling and, in general, have good workability. Although it is possible to subject the strip to cold rolling thickness deformations of the order of 75%, without any intermediate annealing, rolling with annealing after every 35–40% cold rolling reduction yields better results. The efficiency of densification and changes in the pore morphology during the cold rolling of the porous strip have also been discussed.
