Purpose: The main object of this study is to establish the influence of severe plastic deformation on the microstructure evolution and properties of polycrystalline copper Cu99.99. Design/methodology/approach: Polycrystalline copper Cu99.99 was deformed by cyclic extrusion compression (CEC), equal channel angular pressing (ECAP) and hydrostatic extrusion (HE). Additionally the combination of these...
Purpose: The objective of this work present the characterization of microstructure and properties of consolidated powder AgSn7.5Bi0.5 by using composition of cyclic extrusion compression (CEC) and hydrostatic extrusion (HE) methods. As the final product the wires of 3 mm in diameter were obtained. The comparison of powder properties after CEC deformation and after the combined deformation CEC and...
Purpose: The aim of this paper is to study the effect of the preparation procedure for the samples of five engineering polymers on the values of offset yield stress at 0.2% strain (σ02), tensile stress at yield (σy), and tensile stress at break (σB) as well as tensile strain at yield (εy) and tensile strain at break (εB). Design/methodology/approach: A single-screw extruder was used to obtain films...
