Abstract
Inverse pole figures have been made from OFE copper and 70:30 brass samples which were deformed to a von Mises equivalent strain of 1.5 in wiredrawing, compression, and torsion. Measurements were taken from the plane normal to the axis of maximum or minimum principal strain for the cases of tension and compression, respectively. We studied three sections for the specimens deformed in torsion, namely the planes normal to the three cylindrical coordinate axes (Z, R, and π). Our results were consistent with the literature data for both wiredwaring and compression. In wiredrawing we found a duplex fiber texture of [001] and [111] orientations. The amount of the [001] texture was much less for the 70:30 brass. A [011] fiber texture developed in both materials in compression. For the OFE copper, the [011] texture spread toward [113]. In the case of the 70:30 brass there was a spread toward [111]. The inverse pole figures we obtained from the torsion samples had similar trends for both copper and brass. Data from the section taken normal to theR axis showed no distinct preferred orientation. For both materials the Z-section had an increased concentration of [111] poles and a distinct absence of [011] poles. In the case of the copper there was also a slight [001] component. Finally, we found the [011] component in the π-section. This section was also characterized by a lack of [001] or [111] orientations.
