Abstract:
A process for producing a fcc metal consisting of copper having random orientations comprising cross rolling a metal containing copper, which is performed to achieve a total draft of at least 20%, with the rolling axis being offset at 15.degree. or more in each pass to a total offset of at least 90.degree., and subsequent full annealing which is accompanied by recrystallization, said fcc metal satisfying the relations:I.sub.(200) /I.sub.(111).ltoreq.2.3 andI.sub.(220) /I.sub.(111).ltoreq.1.0where (111), I(200) and (220) are the integral intensities of (111), (200) and (220) faces, respectively, of crystal faces as measured by X-ray diffractiometry.
