Welding is a suitable and better process to manufacture complex objects for aerospace, naval, automotive structures. Service conditions complexity in load acting force the manufactures make joints between dissimilar materials. Thus, there need efficient welding techniques form sound an understanding of imperfections their effects. In this study attempt has been made joining feasibility aluminum...

Se ha estudiado el comportamiento tribológico de materiales compuestos matriz metálica aluminio (AA5083)/nano-Al2O3 con un porcentaje refuerzo variable 2, 4, 6 y 8% en peso partículas nano-Al2O3. Los Al/nano-Al2O3 se prepararon utilizando una ruta colada por agitación. Las imágenes microscopía electrónica barrido (MEB) los sugirieron dispersión casi uniforme las nanopartículas la Al. El al desg...

Abstract An Al-5Mg alloy (AA5083) block, deposited over an AA6061 substrate by wire-arc additive manufacturing, was electrochemically tested along two different cross-sectional planes cyclic polarization in 3.5 wt.% NaCl. The layers and the interlayer boundaries showed similar behavior regardless of direction. corrosion both mainly attributed to presence relatively coarse intermetallic Al(Fe, M...

The demand for aluminum alloys is increasing, as are the demands higher strength, with aim of using lighter products a greener environment. To achieve high-strength, corrosion-resistant alloys, melt rapidly solidified melt-spinning technique to form ribbons, which then plastically consolidated by extrusion at elevated temperature. Different chemical compositions, based on adding transition-meta...

The semi-solid state casting procedure was used to manufacture as-cast AA5083, 1 and 2 wt.% of aluminosilicate reinforced composite material. After solidification, developed materials were subjected shock wave treatment in the subsonic wind tunnel. Various techniques evaluate change exposure, including mechanical structural analysis, which is a field dedicated study vibrations other material pr...

A front automobile fender with a negative angle was trial produced via rapid superplastic forming (SPF) technology. The tensile test of industrial AA5083 carried out at elevated temperatures, and the results showed that maximum elongation 242% 480 °C/0.001 s−1. rigid-plastic constitutive model SPF process established. Initial dies preforming final were designed. finite element method (FEM) used...
