The behavior described by Hu of a sharply decreasingr-value as the strain increased in a tensile test has been confirmed in two strongly textured steels, but only for conditions of discontinuous yielding. It does not occur in the absence of interstitial elements when yielding is homogeneous. The present work shows that two distinct anisotropies exist, one in the Luders range and one in subsequent uniform deformation. Possible reasons for this behavior are discussed. The enhanced anisotropy due to discontinuous yielding does not confer benefits in terms of improved drawability and it is recommended that prestrained or temper rolled material should be used when determingr-values.
