“…When La2O3 particles are introduced into the aluminum matrix during FSP, they disperse uniformly, leading to the formation of a composite material with enhanced mechanical properties.Experimental studies have demonstrated a notable improvement of 22.78% in the tensile strength of aluminum-La2O3 composites produced via FSP. This enhancement can be attributed to the effective reinforcement provided by the dispersed La2O3 particles, which act as strengthening agents within the aluminum matrix [47]. The uniform dispersion of La2O3 ensures consistent mechanical behavior throughout the material, resulting in improved tensile strength and resistance to deformation.…”

This study investigates the advancements in Aluminum-Based Composite Manufacturing through the incorporation of lanthanum oxide (La2O3) reinforcement using the Friction Stir Process (FSP). The pivotal role of precision machining, particularly the vertical milling machine, in executing FSP is emphasized. Specific parameters, including pin diameter, tool tilt angle, and rotational speed, were meticulously selected to ensure optimal performance. The uniform distribution of La2O3 particles within the composite matrix highlights the effectiveness of the fabrication process, indicating proper mixing and dispersion techniques. Experimental findings reveal significant improvements in mechanical properties, with a notable 22.78% enhancement in tensile strength, a significant 35.21% increase in hardness, a noteworthy 24.44% improvement in fatigue strength, and a substantial 28.68% increase in wear resistance observed in aluminum-La2O3 composites produced via FSP. These results underscore the potential of leveraging FSP for aluminum-based composite manufacturing, offering opportunities for the development of high-performance materials with enhanced mechanical properties and durability.

This paper explores the revolutionary approach of enhancing aluminum composite manufacturing through the integration of Cr2O3 reinforcement using the Friction Stir Technique. The pivotal role of the vertical milling machine in executing Friction Stir Processing (FSP) is emphasized, detailing precise parameters crucial for achieving optimal results. The even dispersion of Cr2O3 throughout the matrix is highlighted as essential for ensuring consistent mechanical and chemical properties, enhancing overall strength, durability, and resistance to corrosion. Experimental findings reveal significant improvements across multiple mechanical properties, including a remarkable 21.56% increase in tensile strength, a notable 36.89% enhancement in hardness, a significant 24.33% improvement in fatigue strength, and a substantial 29.04% increase in wear resistance. These results underscore the effectiveness of Cr2O3 reinforcement via FSP in revolutionizing aluminum composite manufacturing, offering a pathway towards the development of high-performance materials with diverse industrial applications.

Inconel 825 is a prominent Ni-Fe-Cr based superalloy finds application in aerospace, defense, automotive, nuclear, marine industries. This article investigates ‘weld strength’ and ‘weld bead characteristics’ of Inconel 825 weld specimens welded using the gas tungsten arc welding (GTAW) process. The welding speed (V), welding current (I), gas flow rate (GFR) and arc length (N) are considered as GTAW parameter and their effect has been examined on the weld characteristics. Welding speed and welding current has been identified as the most influential factor on process characteristics; increased welding current combined with lower welding speed enhances the penetration (P) and ultimate tensile strength (UTS) of the weldments. To obtain a favorable parameters setting that satisfies both the criterion simultaneously i.e. maximizing weld strength for optimum weld bead geometry, a hybrid optimization approach employing desirability function coupled with grey relational analysis (DF-GRA) is proposed. Satisfying all the objectives simultaneously, the approach provides an optimum weld parameters setting of (I3−V1−GFR2−N1:120 A−180 mm/min−9 l/min−2 mm) resulting an improvement of 4.15 % in penetration (P), 5.12 % in front width (FW), 19.74 % in front height (FH), 1.29 % in ultimate tensile strength (UTS), and 2.9 % in percentage elongation (%E) on validation. Upon comparison, the algorithm outperforms the optimization results of both DF and GRA approach suggesting its robust nature. Overall, the DF-GRA hybrid approach is found simple and effective that includes the ignored robustness of the desirability approach.
