Cyclic-induced Ductility in Zinc

IT is known that differences exist between deformation produced in metals by steady stress and that due to cyclic stressing1. For example, the lattice distortions revealed by X-ray diffraction patterns and the laws of work-hardening produced by the two modes of stressing are distinctly different. These two types of deformation have been studied extensively but separately. In the work reported here, both steady and cyclic deformation were applied simultaneously, with some striking effects in the resultant behaviour. It was observed that, under the influence of an added cyclic stress, the metal could withstand strains more than 100 per cent greater than those possible with unidirectional straining.
