Wire and arc additive manufacturing cold metal transfer® enable the defect-free soldering of poorly weldable alloys, such as AA6061. Thin-walls have been successfully built with two deposition strategies that is either a back forth movement torch (alternate vectors) or repeating along one direction (unidirectional vectors). The obtained macro- micro-structures are highly dependent on WAAM proce...

The synthesis of agro-waste reinforced metal matrix composites is now very common among researchers because their cost effectiveness, excellent properties and wide industrial applications. This study synthesized a hybrid aluminium 6061 composite with particulates silicon carbide, SiCp carbonized coconut shell, CCSP as reinforcement combined in the ratio 1:1, determined effect combining CCSp rei...

Friction Stir Welding (FSW) is a solid state process widely used to join dissimilar aluminium alloys. High quality and strength joints can be fabricated using this technique when compared to other conventional methods. The welding parameters play major role in determining the quality of the weld. This paper aims in presenting the effect of heat input on tensile properties of the joints between ...

In this study, Al-Mg-Si alloy AA6061-T6 plates were joined in a seawater environment using the Submerged Friction Stir Welding (SFSW) technique, and process parameters optimized Taguchi L9 orthogonal arrays (OA). The considered tool rotational speed, transverse pin geometry. MINITAB-17 software was used to analyze responses signal-to-noise (S/N) ratio analysis of variance (ANOVA). optimum for t...

The Metal Matrix Composite (MMC) technique is the most effective contrast method when compared with other techniques. By using of high energy stir casting, Aluminium alloy Al2219 reinforced various percentages Si3N4 (0, 3, 6, and 9 %) particles. X-ray diffraction along Scanning electron microscope was performed to characterize composite. mechanical thermal behaviours such as differential analys...

Alternative methods for dissimilar metal joining particularly aluminium and copper have gain interest in manufacturing sectors. Friction stir spot welding was carried out on the AA6061 C11000 wires of 2 mm diameter. This research paper reported results microstructures mechanical properties spot-welded joints, also special attention is provided electrical resistivity welds. The reveal informatio...

To provide an understanding of how compositional variations affect the characteristics of coarse intermetallic particles in 7xxx alloys, three Al-Zn-Mg-Cu-Zr aluminium alloy plates with different Zn, Mg and Cu contents were studied by optical microscopy based image analysis, scanning electron microscopy (SEM), energy disperse X-ray spectroscopy (EDS) and differential scanning calorimetry (DSC)....

The Al-Zn-Mg alloy comes under the aluminium alloy; it possesses good capability of age hardening and superior strength in contrast to other alloys. numbers creep aging experiments are conducted with support different temperature levels such as 180, 200, 2000°C. effects tests reflected on tensile test fatigue tests; stress directly affects characteristics, mechanical strength, performance alloy...
