Corrosion behaviour of aluminium alloy inhibited by henna was investigated by using weight loss analysis, Fourier Transform Infrared (FTIR), electrochemical impedance spectroscopy (EIS) and potendiodynamic polarization study. Lawsonia inermis or also known as henna was extracted by using ethyl acetate and methanol. The result from these characterization shows that henna extracted in ethyl aceta...

The corrosion, microstructure, and hardness of nanocrystalline AA5083 were compared to that conventional AA5083-H116 consolidated gas atomized powder. was produced by consolidating high-energy ball milled powder with two methods: cold compaction spark plasma sintering. Electrochemical impedance spectroscopy, cyclic potentiodynamic polarization, Mott-Schottky analysis, immersion tests followed s...

Equal channel angular Pressing (ECAP) is an innovative technique for developing ultrafine-grained microstructures first developed by Segal et al in 1981 in the former Soviet Union. The ECAP method consists of two channels that intersect at an angle, generally comprised between 90◦ and 135◦ . The deformation is produced by shear as the billet is extruded through the channels. One of the geometri...

There are two laser welding mechanisms, keyhole mode and conduction mode. Keyhole welding is widely used because it produces welds with high aspect ratios and narrow heat affected zones. However keyhole welding can be unstable, as the keyhole oscillates and closes intermittently. This intermittent closure causes porosity due to gas entrapment. Conduction welding, on the other hand, is more stab...

Because of their superior ballistic and mechanical properties, lightweight materials like titanium alloy Ti-6Al-4V and aluminum alloy AA5083-H116 have been frequently used for aerospace and military applications. Tests of ballistic limit velocity are limited by expensive nature of the experimental setup, and indeed, that can be resolved by adopting numerical simulations. Numerical study involvi...

Al-5Mg-0.8Mn alloys (AA5083) with various iron and silicon contents were cast under near-rapid cooling and rolled into sheets. The aim was to study the feasibility of minimizing the deteriorating level of the harmful Fe-rich phases on the mechanical properties through refining the intermetallics by significantly increasing the casting rate. The results showed that the size and density of the in...

recently, offshore and ocean engineering have been dealing with novel materials that play a significant role in reducing the weight of structures used in the ship construction industry. 5xxx series of aluminum alloys are of the novel alloys are suitable for construction of ship hulls and the topside structures of offshore platforms. within different 5xxx aluminum alloys, aa5083 is of great impo...

High-entropy alloy particles (HEAPs) can markedly enhance the mechanical properties of metal matrix composites (MMCs). In this study, AA5083/Al0.5CoCrFeNi HEAPs MMCs with different contents (0, 1, and 3 wt%) were prepared via a stir-casting, then these sheets hot rolled (573 K) cryorolled (77 K), respectively. The measured by tensile testing microhardness test. Additionally, their microstructur...

Abstract This paper investigates the low velocity impact performance of AA5083 using ABAQUS software. The resistance was measured in terms depth indentation created over AA5083. Low-velocity results indicates, that angle inclination resisting body have a great influence on properties. analysis study carried out for different orientations alloy plate with respect to horizontal datum namely 30°,6...

Abstract Low cycle fatigue (LCF) properties were investigated for a novel cryomilled AA5083 aluminum composite with duplex coarse and ultrafine grain sizes reinforced boron carbide particulates, referred to as trimodal material. Fully reversed cyclic tests conducted under plastic strain control at amplitudes from 0.15 0.6 pct using constant rate in servo-hydraulic testing system. A nonlinear el...
