The purpose of the present investigations was to perform a detailed x-ray analysis on a bulk specimen of a fcc metal deformed by rolling at room temperature and on powder of the same material deformed by compaction, and to compare these results with those previously obtained on cold worked filings. Pure copper was chosen for this study since it is known to produce only a small quantity of stacking faults by filing at room temperature. The residual elastic strain in the surface of the bulk-copper should be the predominant factor determining the shifts of the powder pattern peaks from the bulk specimens, whereas residual stresses should be absent or small in the compacted copper powders.
