EFFECTS OF ROTARY SWAGING, WIRE DRAWING AND THEIR COMBINATION ON THE RESULTING PROPERTIES OF NICKEL-ALLOY WIRES

Original language description

This paper investigates the influence of drawing and rotary-swaging parameters, such as the area reduction, on the tensile properties of nickel-alloy wires. Rotary swaging and wire drawing were used to improve mechanical properties. Furthermore, the effect of the combination of these processes on the resulting hardness of the cross-sections of wires was studied. In the case of rotary swaging, the highest amount of cold deformation (an increased value of hardness) is located in the middle of the wire. This can be explained with the formation of deformation cones oriented to the centre of the wire. On the other hand, the highest amount of cold deformation in the case of drawing is located on the surface (just under the surface layer) of the drawn wires. As a result, our interest is focused on achieving large cross-sectional reductions during the wire-drawing process. In addition, the largest approach angle is used in order to avoid redundant shear. Thanks to the combination of the rotary swaging and wire drawing, there are negligible differences in the hardness across the wire diameter. The mechanical properties, the microstructures in the longitudinal and transverse directions and the hardness profiles (HV) of pure-nickel-alloy (Alloy 200) wires were compared in this investigation.
