KCl Whiskers (grown in <100> direction) thicker than about 70μ show logarithmic stress-strain curves, which are caused by the propagation of Luders bands. The front velocity of a Luders band is nearly constant for the constant tensile strain rate in spite of the remarkable increase of the flow stress during its propagation. The average strain in a Luders band increases with its propagation. On the other hand, whiskers thinner than about 70μ show remarkable serrated yielding phenomena. It is shown that both the logarithmic stress-strain curve and the serrated yielding can be interpreted on the basis of experimental facts and on the cross-slip mechanism which may be caused by the stress field of screw dislocation alignments in Luders bands.
