“…These welding features happened in all of the RFW tests of the similarly and dissimilarly welded steels. This welding behavior was, contrarily, different to the most common rotary friction welds, for which the flow of the material moved from the center of the rod and widened near the surface of the rod [14]. In the same manner, it can be observed that the welding zone is enclosed by a larger zone.…”

“…Even empirical and numerical models have been developed to estimate the scope and optimization of this type of technology [10][11][12][13]. Also, novel microstructural characterization techniques to analyze the resulting microstructure in the different formed zones (i.e., the thermomechanical-affected zone (TMAZ), the thermal-affected zone (TAZ), and the welded zone (WZ)) after RFW have been applied [14].…”

Advanced high-strength steels (AHSSs) are designed for meeting strict requirements, especially in the automotive industry, as a means to directly influence the reduction in the carbon footprint. As rotary friction welding (RFW) has many important advantages over other welding technologies, it plays an important role in the automotive sector. On the above basis, in this work, combinations of the first (complex phase (CP)), second (TWIP (TW)), and third (quenched and partitioned (Q&P)) generations of similar and dissimilar high-alloyed advanced steels have been joined by the RFW process. Having a specific microstructure, rods of CP/CP, Q&P/Q&P, CP/TW, and Q&P/TW steels were welded by employing a homemade adaptation machine under fixed parameters. Microstructural characterization has allowed us to corroborate the metallic bonding of all the tested advanced steels and to identify the different zones formed after welding. Results indicate that the welding zone widens in the center of the workpiece, and under the current friction action, the intermixing region shows the redistribution of solute elements, mostly in the dissimilarly welded steels. Furthermore, because of their complex chemistry and the different mechanical properties of the used steels, dissimilarly welded steels present the most noticeable differences in hardness. The TWIP steel has the lower hardness values, whilst the CP and Q&P steels have the higher ones. As a direct effect of the viscoplastic behavior of the steels established by the thermomechanical processing, interlayers and oxidation products were identified, as well as some typical RFW defects. The electrochemical response of the welded steels has shown that the compositional and microstructural condition mostly affect the corrosion trend. This means that the dissimilarly welded steels are more susceptible to corrosion, especially at the TWIP–steel interface, which is attributed to the energy that is stored in the distorted microstructure of each steel plate as a consequence of the thermomechanical processing during RFW.

“…Carrying out such studies is of great importance, since in connection with the development of super-deep wells, the requirements for the reliability of drill pipe welded joints increase. Previous works was focused on the study of the evolution of the structure and the mechanism of formation of welded joints from 32G2 and 40 KhN [13,14], the study of texture in TMAZ [15], as well as residual welding stresses [16]. In [17], the influence of the friction pressure on the structure characteristics the and tensile properties of these welded joints was studied separately.…”

In this work, pipe billets with a diameter of 73 mm and a wall thickness of 9 mm from steels 32G2 and 40KhN are friction welded with an aim to optimize the process parameters. The friction pressure, the forging pressure and the length of the fusion varied. After the implementation of various welding modes, tensile tests and metallographic studies were carried out. The optimal welding parameters have been established, which make it possible to obtain tensile strength at the level of the 32G2 base metal. The study results of the microstructure and SEM fractographs after the optimal welding mode are presented.
