Subject Keywords Zinc crystals; Mercury; Metals -- Brittleness
Abstract: A study has been undertaken to investigate the loss of ductility and modified work hardening characteristics of zinc single crystals coated with mercury. Important results of tensile tests performed under fixed experimental conditions are summarized to be: (1) increase in critical resolved shear stress, and increase of work hardening slope in stage A and stage B (2) decrease in transition strain from stage A to stage B (3) decrease in fracture stress and fracture strain. The results have been interpreted in the context of the present understanding of deformation theory of C.P.Hex. metals. In addition, relevant mechanisms for crack initiation have been studied with the aid- of microscopic observations of deformed crystals.
