Mechanical Characteristics and Structure of Highly Deformed Zinc

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