“…The mechanical properties of ECF are intimately linked to its microstructural features, including grain size, grain morphology, twin, the size of grain boundaries, and the preferential orientation of crystal planes. − In polycrystalline materials, each grain exhibits a distinct crystal orientation and these orientations are randomly distributed. , However, in certain specific cases, due to the different growth rates of each crystal plane, the grains will be arranged to some extent according to certain specific orientations, exhibiting a phenomenon of preferred orientation of crystal planes at the macroscopic level, and it is called texture. , Copper possesses a face-centered cubic structure (FCC), and the prevalent textures in ECFs are (111), (100), and (110). Numerous studies reveal a connection between the mechanical properties of ECF and texture, but theoretical research regarding the intrinsic correlation between texture and mechanical properties is noticeably scarce. − …”

Electrolytic copper foils (ECFs), owing to their excellent mechanical properties and conductivity, have become an indispensable component as an anodic current collector in lithiumion batteries. ECFs often show texture properties, but the intrinsic relationship between the texture and mechanical properties is rarely reported. The authors find a conspicuous preference for the (100) crystal plane in 6 and 8 μm ultrathin ECFs with high elongation. And certain ECFs even exhibit a positive correlation trend between elongation and the (100) relative texture coefficient. It can be inferred that enhancing the (100) texture contributes to the improvement of the elongation in ECFs. Moreover, the Schmid factor values for the ( 111), (100), and ( 110) planes are calculated. The results revealed that the number of slip systems that can be activated under different tensile directions of the (100) plane is the largest, while the number of (110) plane is the least. It implies that under equivalent conditions, ECFs with (100) plane orientation are more prone to undergo plastic deformation, thereby facilitating high elongation. In contrast, the (110) plane orientation contributes to a high tensile strength.

“…The microstructure of the welded joint reveals that ultrasonic vibration promotes the reduction of secondary phases and element homogenization. Wang et al enhanced the grain shape of the weld joint using the ultrasonic-assisted laser welding technique and analyzed the beneficial impact of equiaxial grains on the mechanical properties of Inconel 690 weld joints from a fracture perspective [29] . However, despite its conventionality, the ultrasonic-assisted GTA welding of Inconel 690 still requires further investigation.…”
