The pole figures and ODFs of the specimen processed by the NCD sequence showed typical drawing and rolling textures.
From the EBSD results, the higher low angle grain boundaries length per unit area and smaller average grain size of the specimen processed by the non-circular drawing sequence were obtained than those of the specimen processed by the wire-drawing process for the 8th pass.
From the EBSD results, the areal fraction of the low angle grain boundaries (1.12 μm−1) of the specimen processed by the NCD was higher than that (0.78 μm−1) of the specimen processed by the WD for the two-pass.
Mechanical properties, microstructure and texture evolution of the specimen processed by the newly proposed process and conventional wire drawing (WD) were investigated by tension test, electron backscattering diffraction (EBSD), and X-ray diffraction (XRD) for comparison.
In addition, the ultimate tensile strength value of the specimen processed by the continuous hybrid process was 23.9% higher, although the elongation was slightly lower than the one produced by the conventional wire-drawing process.
Mechanical properties and microstructure evolution of the specimen processed by the sequence were investigated by tension, Vickers micro-hardness, electron backscattering diffraction (EBSD), and fatigue tests compared with those for the conventional wire-drawing process.
