Abstract

The texture of previously-studied copper of grain sizes 3.4, 15 and 150 µ m has been measured, and compared to copper either mechanically processed to “randomize” texture, or cast in an equiaxed condition. Work-hardening behavior was also determined for the latter two types of material. The 3.4 µ m material was found to be very weakly textured, yet its stress-strain curve differed considerably from the Taylor-predicted curve based on a <111> single crystal. More strongly fiber-textured material, such as the 150 µ m material, and also the weakly-textured cast material of 405 µ m grain size, agreed much more closely with the Taylor prediction. It was concluded that any texture effects on work hardening in copper are overwhelmed by grain size effects.
