The Aluminium Alloy (AA7050) hybrid composites (AAHC’s) reinforced with 2-10 wt.% ZrB2 ceramic particles, 1-5 wt.%Al2O3 particles and 0.5-2.5 wt.% MWCNT in novel Vibro-compo casting through liquid casting route. The ZrB2 and Al2O3have been introduced in the conventional method, and MWCNT is injected by argon gas. Then, the stirring process wascarried out in different temperatures to enhance wettability between reinforcements and matrix. The developed AAHC’s werecharacterised using a Scanning Electron Microscope (SEM) and Energy-dispersive X-ray spectroscopy analysis (EDS). Themechanical properties like hardness, tensile, impact and fatigue tests were performed on all the casted samples elaborately. The dispersion of ZrB2 ceramic particles and its implanting over the ductile Al7050 matrix was effectively obtained, whichshown superior mechanical properties when compared to monolithic Al7050 alloy. The specimen contained 1.5%MWCNT +6%ZrB2 + 3%Al2O3 reveals the greater tensile strength, which is 30.73% higher than the base material. Besides, the EDSresults ensured the manufacturing of Al 7050/MWCNT + ZrB2+Al2O3 metal matrix composites successfully, and no otherintermetallic phases were identified.

In this present work, an attempt was made on optimising the Resistance Spot Welding (RSW) process parameters for joiningtwo dissimilar combinations of AISI 304 and AISI 1020 grade steel with each other. Experiments were conducted by varyingthe three weld process parameters such as welding current, pressure and welding time. The integrity of the weld joints wasevaluated mechanically and metallurgically. Tensile shear fracture, nugget diameter, and hardness properties were examined. Macrostructure, Microstructure, and Scanning Electron Microscopy (SEM) analysis were carried out on the tested samplesto validate the type of fracture occurred. Maximum nugget diameter and maximum tensile fracture of 6.666 mm and 10.5 kNwere achieved respectively. The experimental results confirmed the validity of the used Response Surface Methodology appliedfor optimising the welding process parameter in the RSW process. The Response Surface Methodology (RSM) results showthat the weld current is the most significant factor for Tensile Shear Fracture Load (TSFL) and nugget diameter, followed byweld pressure and time.
