“…Since the welding temperature increases with an increase in the tool rotation speed, which leads to the formation of a thicker IMCs layer at the Ti/Al interface at a higher tool rotation speed. As a result, higher weld residual stress and distortion occurred at a higher tool rotation speed due to a remarkable volume variation of the IMCs layer [24][25][26]. As a result, the first-pass weld cracks under the plunge force of the tool during the second-pass welding at the higher rotation speed.…”

“…A large quantity of heat generated by the shoulder leads to a high welding temperature at the upper part of the workpiece, which results in a thick IMCs layer. The thick IMCs at the joint interface lead to a remarkable volume variation and resulting in large residual stress [24][25][26]. However, the relatively lower tool pin heat generation and thermal conduction of Ti alloy lead to a lower temperature of plastic material at the lower part of the weld, which is prone to form voids and unbound defects.…”

Double side friction stir welding (DS-FSW) was used to join TC4 titanium alloy and 2024-T4 aluminium alloy having dissimilar medium-thick plates with a thickness of 8 mm. The microstructure and mechanical properties in medium-thick Ti/Al dissimilar DS-FSW joints were systematically studied. It revealed that the diffusion-type Ti/Al interface was mainly formed when the rotating speed is low. While intermetallic compounds layers were formed at the Ti/Al interface due to the high welding temperature and intense mechanical mixing at a relatively high rotating speed. The maximum tensile strength of medium-thick Ti/Al dissimilar DS-FSW joint is 265 MPa achieved at the rotation speed of 300 rev min -1 , which is 58.9% of the base material of 2024-T4 aluminium alloy.

Summary This work targets the design of a novel composite nanomaterial (NCM) based on the exchange of electro current between magnesium oxide and yttrium oxide on the surface of the synthetic self‐assembly (graphene oxide/carboxymethyl cellulose) for supercapacitors, biosensors, and photocatalytic. The different techniques utilize for the characteristic synthesized NCM such as morphology, optical properties, and structural evidence. The electrochemical behaviors and the optical properties perform emphasize the improvement of the electron transfer via the incorporation of the two metal oxides on the surface of the self‐assemble. The photocatalytic efficiency records at 85% after 80 min, and the rate constant documents at 4 × 10−3 min−1 due to the ease of the oxygen reactive species generation for removing the pollutants. The impedance spectroscopy data emphasize the development of the surface and electron transfer that enable it to be a promising candidate for supercapacitors applications. The capacitance value of CNM has been documented at 58.81 nF/cm2, also the biosensor applications for glucose and D‐galactose are detected by UV–Vis spectroscopy and the electrochemical method. From the results, the CNM is a promising candidate for water treatment membrane, supercapacitors manufacture, and biosensors applications.

“…The current trend in industry is toward making multifunctional components by integrating several similar and dissimilar materials. The welding and joining of dissimilar alloys is a crucial procedure in the production of hybrid structures, and a number of researchers have been prompted to look at the welding of various dissimilar alloy combinations [1][2][3][4][5]. Superior mechanical properties and oxidation resistance at high temperatures have made Inconel 718 (IN718), a nickel-based superalloy, a useful material with a range of aerospace applications, such as in aeroengine and gas turbine design [6,7].…”

In a dissimilar welded joint between Ni base alloys and titanium, creep failure is a potential concern as it could threaten to undermine the integrity of the joint. In this research, the mechanical heterogeneity of a Pulsed TIG welded joint between commercially pure titanium (CpTi) and Inconel 718 (IN718) with a vanadium (V) interlayer was studied through a nanoindentation technique with respect to hardness, elastic modulus, and ambient temperature creep deformation across all regions (fusion zones and interfaces, mainly composed of a dendritic morphology). According to the experimental results, a nanohardness of approximately 10 GPa was observed at the V/IN718 interface, which was almost 70% higher than that at the V/CpTi interface. This happened due to the formation of intermetallic compounds (IMCs) (e.g., Ti2Ni, NiV3, NiTi) and a (Ti, V) solid solution at the V/IN718 and V/CpTi interfaces, respectively. In addition, nanohardness at the V/IN718 interface was inhomogeneous as compared to that at the V/CpTi interface. Creep deformation behavior at the IN718 side was relatively higher than that at different regions on the CpTi side. The decreased plastic deformation or creep effect of the IMCs could be attributed to their higher hardness value. Compared to the base metals (CpTi and IN718), the IMCs exhibited a strain hardening effect. The calculated values of the creep stress exponent were found in the range of 1.51–3.52 and 2.52–4.15 in the V/CpTi and V/IN718 interfaces, respectively. Furthermore, the results indicated that the creep mechanism could have been due to diffusional creep and dislocation climb.
