Mechanical Characteristics and Structure of Highly Deformed Zinc

The paper contains a set of experimental data on the influence of the KOBO extrusion (extrusion with simultaneous cyclic torsion) on mechanical properties of pure zinc and proves that they can be controlled in order to achieve the desired final values, while tensile characteristics may either show m...

Summary:The paper contains a set of experimental data on the influence of the KOBO extrusion (extrusion with simultaneous cyclic torsion) on mechanical properties of pure zinc and proves that they can be controlled in order to achieve the desired final values, while tensile characteristics may either show monotonic course or contain the Lüders-type effect. It has been found that the mechanical properties of the KOBO extruded zinc are not linked to the grain size, thus proving the hypothesis about the dominating role of over-equilibrial concentration of point defects (including their clusters).
