Abstract
Substantially completely deoxidized, consolidated dispersion-strengthened copper stock of sizable cross section and particulates capable of being thus consolidated into such stock are shown. The stock exhibits ductility substantially greater than that of otherwise corresponding stock which contains about 100-500 ppm of available oxygen. Also shown is a staged powder deoxidation process using hydrogen or like reducing gas followed by the sequestration of remaining available oxygen with a minute proportion of diffusible, normally solid oxygen getter.
