Summary: Friction stir welding (FSW) is a new technique that uses friction and material deformation to generate thermal energy for solid-state joining. It has advantages such as reduced material waste, energy saving, and decreased residual stresses. However, difficulties remain in welding high-density polyethylene (HDPE) using FSW.

Summary: This study suggests that friction-stir welding (FSW) is an effective method to improve the resistance of hydrogen embrittlement in Fe-17Mn alloy. Despite the active α' martensitic transformation, FSW specimens exhibited enhanced resistance to hydrogen embrittlement during hydrogen-charging and tensile deformation. The presence of numerous ε phases and higher initial dislocation density in the FSW specimens reduced hydrogen diffusion and accumulation, resulting in shallow hydrogen-related brittle fracture. Additionally, FSW-induced grain rotation and higher ce/ae ratio led to stronger resistance against boundary decohesion and suppressed hydrogen-induced crack growth.

Summary: This paper scrutinizes the analysis of energy flow during FSW/P and finds that the majority of energy dissipates as heat into the tooling and clamping system. Only a small portion of energy is effectively used for welding/processing. The study suggests that selecting the right anvil material can enhance energy efficiency.

Summary: This study aimed to investigate the effect of high-heat-input friction-stir welding (FSW) on microstructural evolution. The FSW process resulted in an unusual structural response due to the extreme deformation conditions. A commercial 6013 aluminum alloy was used as the material, and FSW was conducted at a high spindle rate and extremely low feed rate, with the use of a Ti-6Al-4V backing plate to minimize heat loss. The high-heat-input FSW led to the formation of a fine-grained layer at the upper weld surface, attributed to the stirring action of the FSW tool. Furthermore, continuous recrystallization was observed to be retarded, likely due to the competition between recrystallization and recovery at high temperatures.

Summary: The study found that sound FSW joints can be obtained between an AA6061 aluminum plate and a thick MMC plate with 40% SiC particles. The joints withstand tensile testing, with ductile failure occurring in a soft region on the alloy side. Metallographic examination on the MMC side after FSW showed curved bands with lower frequency of SiC particles and hardness.

Summary: Joining dissimilar materials in industrial applications, especially in the transport industry, using friction stir welding (FSW) and friction stir spot welding (FSSW) has shown great potential. While there are difficulties in joining different aluminum alloys, it is relatively easier compared to joining materials with very differing properties.

Summary: An online detection technology has been developed for real-time control of friction stir welding. Through the collection of three-dimensional forces exerted on the material during welding, the relationship between forces and welding quality was studied. The results showed that traverse and lateral forces follow an elliptical curve, while the plunge force fluctuates at the same frequency as the spindle rotational speed. The ratio parameter increased significantly when tunnel defects occurred, while the fluctuation period remained consistent with normal welding.

Summary: To reduce the cost of extracting petroleum from ultra-deepwater sources, using 7175 aluminium alloys instead of steels for risers is being considered. Friction stir welding (FSW) is being applied to develop high-strength, corrosion-resistant weldments for connecting 7175 Al riser flanges and pipes. However, obtaining high-performance thick plate 7175 Al alloy joints via FSW presents challenges due to decreased welding speed and weakened mechanical properties in the heat affected zone.

Summary: This paper proposes and explores a hybrid manufacturing method for the friction stir welding (FSW) process and extrusion-based additive manufacturing (EAM) technology. The effects of FSW process using two different welding tools on the mechanical behaviors of 3D printing polymer parts are compared and investigated, and the corresponding mechanism is analyzed. The results show that the appropriate welding tool is beneficial for eliminating anisotropy and decreasing porosity of 3D-printed parts, thus verifying the improving effects of the FSW process on the mechanical behaviors of EAM parts. This study may provide assistance in modern industrial manufacturing for the processing of large custom components.

Summary: This study investigated the eutectoid decomposition of gamma-U phase into alpha-U and gamma'-U2Mo phases in three U-Mo based alloys. Detailed crystallographic analysis was performed on the decomposed products, revealing orientation relationships and lattice correspondence between parent and product phases. Strains within the lattice were found to play a role in controlling the kinetics of phase transformation and morphology of daughter products. Ternary alloy additions with different sizes of solute atoms allowed manipulation of the strain associated with transformation, resulting in changes in the width of product phase lamellae.

Summary: The development of microstructure, texture, and mechanical properties in single and two-phase recrystallized and aged Ni-Cr binary alloys were investigated. The recrystallization of γ-Ni phase was influenced by the deformation texture and the concurrent precipitation of α-Cr phase in the two-phase alloys. The α-Cr precipitation resulted in the hardening of the aged two-phase alloys. The deformation texture after aging could be correlated to the change in stacking fault energy due to Cr content. The dominance of certain recrystallization textures could be explained by the advantage of "oriented growth" offered by the concurrent α-Cr precipitation on grain boundaries.

Summary: Hydrogen diffusion studies in Zr-2.5% Nb alloy pressure tube material are important for modeling localized embrittlement phenomenon. The microstructure of the pressure tube consists of lamellar alpha-Zr and beta-phase with stingers and globules. The diffusivity values for hydrogen in Zr-2.5%Nb alloy along different pressure tube directions were studied, and correlation with the microstructure was analyzed. Neutron radiography was used to study diffusion along different directions, and a theoretical approach was followed for evaluating diffusivity values for the alpha-Zr and beta-Zr phases.
