“…The parameter AR expresses the aspect ratio of an ellipse fitted to the shape of a particle or grain microstructure, its value is the ratio of the major axis to the minor axis of this ellipse fictitious (Eq. 6), and the roundness Rnd is the inverse of Aspect Ratio [17]. has been noticed in another research works, the effect of cold working is not yet discernible, which is evident from the widths of the peaks [18,19].…”

The scope of this work is to investigate the effect of the cold deformation by wire-drawing on microstructure and physical properties of industrial copper wires. Copper wires were provided by E.N.I.CA.Biskra (Algeria). We investigated some wires with different strain levels (as received, 1.20, 2.10, and ε = 3.35). X-ray diffraction, optical microscopy, and electrical resistivity measurement have been used as characterization techniques. We analyzed the photographs using "ImageJ" software and DRX patterns using PM2K software. The results revealed that the cold wire-drawing causes a lengthening of grains along the axis of wire-drawing, and introduced large amounts of defects. The results also showed, on the one hand, the decrease in crystallite size, lattice parameter, and the outer cut-off radius, on the other hand, the increase of the electrical resistivity and the dislocation density in the copper wires.

“…For this purpose, the vector graphics program Inkscape 0.92.4 was used. Then, for the digital images obtained in this way, stereological calculations in the field of quantitative metallography were performed using the Met-Ilo v9.11 program [27][28][29]. Volume fractions Vv of the defined areas of particular structures, mean surface areas of grains and subgrains were determined, and their shape factor was also calculated.…”

The work presents the results of research on the structure of welded joints in the area of heat affected zone (HAZ). Based on precisely performed metallographic tests, the contribution of individual structural components in the area of welds of pipes welded with the induction method was assessed. The volume fraction of individual structural components in various areas of the heat affected zone, the size of the grain formed in the welding process, as well as its shape coefficients were determined. On the basis of metallographic observations, an attempt was made to describe the course of the pressure induction welding process, taking into account the structural changes, phase changes and the recovering and recrystallization processes taking place in this process.

StabIlIty of a lamellar Structure -effect of the true Interlamellar SpacIng on the durabIlIty of a pearlIte colony Stabilność Struktury płytkowej -wpływ rzeczywiStej odległości międzypłytkowej na trwałość kolonii perlituA lamellar microstructure is, beside a granular and dispersive one, the most frequently observed microstructure in the case of metal alloys. The most well-known lamellar microstructure is pearlite, a product of a eutectoidal transformation in the Fe-Fe3C system. The lamellar morphology of pearlite -cementite and ferrite lamellae placed interchangeably within one structural unit described as a colony -is dominant. The durability of the lamellar morphology is much diversified: in the microstructure of spheroidizingly annealed samples, one can observe areas in which the cementite is thoroughly spheroidized, next to very well-preserved cementite lamellae or even whole colonies of lamellar pearlite. The mentioned situation is observed even after long annealing times. The causes of such behaviour can vary. The subject of the previous work of the authors was the effect of the orientation between the ferrite and the cementite on the stability of the lamellar morphology. This work constitutes a continuation of the mentioned paper and it concerns the effect of the true interlamellar spacing on the stability of the lamellar morphology of cementite.
