Abstract:

Extruded aluminium profiles with a variety of different cross-sections are mainly used in lightweight structures for transportation means. Examples are stringer profiles in the fuselage of airplanes or profiles in chassis of trains and cars. Nowadays, the mass reduction of a lightweight structure is an important issue to achieve lower fuel consumption and CO2 emissions. With an increased portion of aluminium profiles the mass of structures can be reduced considerably in contrast to the application of steel parts, due to the lower density of aluminium. However, this is coupled with disadvantage

AbstractThe paper deals with the simulation of cooling processes of the aluminium profiles inside the water quench. Cooling of profile surfaces is performed by water spray, which is created by mixing a water and an air in a nozzles. Formulas were found in literature, modified and applied to a given problem that significantly simplified a solution. The task of numerical simulations was to determine temperature and velocity profile on aluminium profile surfaces for establishing of the heat transfer coefficient which was used as the convective boundary condition necessary to solve the heat transf

In this paper we report the ab-initio theoretical Compton profiles of aluminium nitride (AlN) in the framework of the Hartree-Fock, density functional theory and hybridization of Hartree-Fock to density functional theories using the CRYSTAL03 code. To compare our first ever theoretical data, we have also measured the isotropic Compton profile of AlN, using 59.54 keV γ -rays. The Hartree- Fock scheme-based Compton profile agrees better with the experiment than the other theories. The energy bands, density of states and Mulliken’s population analysis, using the CRYSTAL03 code, are also reported.

The microstructure evolution in commercial AlMgSi alloys during and after extrusion of a simple U-shaped profile has been modelled. The strain, strain rate and temperature along a set of particle paths are taken from FE-HyperXtrude simulations and used as input to the work hardening model ALFLOW, to predict the evolution of the subgrain size and dislocation density during deformation. As soon as the profile leaves the die, the subsequent recovery and recrystallization behaviour is modelled with the softening model ALSOFT. This procedure enables the modelling of recrystallization profiles, i.e.

Abstract Aluminium profiles are widely used in distinct fields since their excellent physical properties, and the quality and efficiency of producing aluminium profiles are largely depending on the extrusion dies.

The assumptions adopted to create the concept of the technological line were specified. A block diagram of the line and drawings showing the s

Abstract:

The current study investigates the effect of a hybrid L-profile aluminium/glass-fiber-reinforced polymer stacking sequence under axial and lateral compression loads. Four stacking sequences are studied: aluminium (A)—glass-fiber (GF)—AGF, GFA, GFAGF, and AGFA. In the axial compression test, the aluminium/GFRP hybrid tends to crush in a more progressive and stable failure than the net aluminium and net GFRP specimens, with a relatively more stable load-carrying capacity throughout the experimental tests. The AGF stacking sequence was second, with an energy absorption of 145.31 kJ, following AGF

Abstract:

This study investigated the chemical characteristics of shallow (0–30 cm) soil profiles under shrubs in areas of dense encroachment and compared them with shallow soil profiles under nearby large trees. Consistent patterns of high soil acidity were found under shrubs, as well as lower litter alkalinity, lower relative concentrations of calcium (Ca2+), lower effective cation exchange capacity, and higher aluminium (Al3+) and sodium (Na+) in the soil profile compared with under trees. Soil pH (CaCl2) was strongly correlated with the Ca content of surface litter. These findings suggest that shrub

Abstract:

The joining of similar and dissimilar AA2014, AA6068 and AA7075 aluminium plates of 6mm thickness was carried out by friction stir welding (FSW) technique. FSW of Aluminium to Aluminium has caught significant consideration from assembling industries, such as Shipbuilding, Automotive, Railway and Aircraft generation. Here, the chosen process parameters are tilt angle (2º), tool rotation speed (900rpm) and transverse feed of (80mm/min) at constant axial force 2kN. An attempt was made to join the similar and dissimilar aluminium plate of 6 mm thickness with a conical tapered tool profile. Then, t

Abstract:

It is challenging to obtain defect free welded joints of Aluminum Alloys with the help of fusion welding processes. In fusion welding, oxide layer of aluminum alloys penetrate inside, which has the tendency to thicken at higher temperatures, which in turn results in the defects like porosity and cracks in the weld joint. In contrast, Friction Stir Welding (FSW) is proved to be a very good solid state welding technique, which has got a worldwide attraction, especially in aerospace industry. FSW doesn’t involve actual melting of the materials, rather the welding is done at visco-plastic state of

An Al2O3-CuO mixture with 75 mol% CuO was selected, aiming at a 10-40vol% reinforcement phase fraction in the final composite, after aluminium infiltration. Molten aluminium infiltration progress was studied as a function of ceramic’s composition, doping, and infiltration time.

Texture evolution during indirect extrusion of cylindrical profiles of an AlSiMgMn aluminium alloy was investigated in the present work. The effect of extrusion temperature on texture development, through-thickness texture variations and texture variations along the length of the extruded profiles were investigated. In all cases a combined 〈100〉 and 〈111〉 fibre texture developed. Generally, the 〈111〉 fibre was sharper than the 〈100〉 fibre. The texture evolution was rather similar along the length of the profile, while the variations through the thickness were considerable. In a region midways
