Pulsed nuclear magnetic resonance proved to be a new complementary technique for the study of moving dislocations in Al-base alloys. Spin-lattice relaxation measurements clearly indicate that fluctuations in the quadrupolar field caused by moving dislocations in Al-base alloys are different compared to those in ultra-pure Al. From the motion induced part of the spin-lattice relaxation rate the mean jump distance of mobile dislocations has been determined as a function of strain. Measurements have been performed on Al-Cu, Al-Li and Al-Zn binary alloys. As a typical illustration of the strength of this technique, this paper reports the results obtained of Al-(1-2 at%) Zn solid solution.

Pulsed nuclear magnetic resonance proved to be a complementary new technique for the study of moving dislocations in b.c.c, metals. From the motion induced part of the spin-lattice relaxation rate the mean jump distance of mobile dislocations has been measured in Vanadium as a function of temperature. The NMR experiments are combined with transmission electron microscopic investigations to reveal the static structure of defects in the samples. The NMR experiments show that the mean jump distance is nearly constant below 230 K whereas it decreases substantially above 230 to 300 K indicating a transition that marks two different mechanisms. NMR observations in combination with TEM support the physical picture that above the transition temperature dislocation segments are stopped between localized obstacles whereas below T c the lattice friction controls the plastic behaviour.
