6063 aluminium alloy is widely used in architectural applications such as window and door frames because of its nice appearance acceptable strength. Its major alloying elements are magnesium silicon. Not many studies focused on the influence plastic deformation content post-processing quality corrosion resistance have been published. Considering that variation chemical composition could propert...

the idea of combining low weight and good mechanical properties has led to efforts to develop a new light fiber/metal laminate (fml) in the last decade. fmls are hybrid composites consisting of alternating thin layers of metal sheets and fiber-reinforced epoxy prepregs. in this study, the effect of fiber orientation on tensile properties of this material is investigated both analytically and ex...

This paper is concerned with the optimization of the surface roughness when milling aluminium alloys (AA6061-T6) with carbide coated inserts. Optimization of milling is very useful to reduce cost and time for machining mould. Potential support vector machine (PSVM) is used to develop surface roughness predicted model. Design of experiments method and response surface methodology techniques are ...

This research paper presents the mathematical model to design a stepped pin profile tool and its durability index. A is being developed by considering tools that should generate same heat as conventional conical varying shoulder diameter ratio (D/d). Aluminum alloy AA6061-T6 with thickness of 6 mm fabricated using butt-type weld configuration newly water cooling medium. The result shows better ...

Folęga, Silesian University of Technology, Faculty of Transport, Katowice, Poland In the present paper, the rate of aluminium evaporation from the Ti-6Al-7Nb alloy during smelting with the use of VIM met...

To achieve reliable welds with minimum distortion for the fabrication of components in aerospace industry laser beam welding is attempted. Laser welding can provide a significant benefit for the welding of Titanium and Aluminium thin sheet alloys of its precision and rapid processing capability. For laser welding, pulse shape, energy, duration, repetition rate and peak power are the most import...

Because of the need for weight reduction in transport industry, in order to save energy as well as to reduce CO2-emission, the use of light weight aluminium sheet is taken increasingly into consideration [1]. But although aluminium is lighter than steel, the formability is less, hence press operations are often more critical. Alloys used are typically 5xxx alloys for inner panels because of the...

Metal matrix composites are in high demand for various applications the industrial sector and engineering firms. Therefore, new materials with enhanced mechanical ecologically favourable characteristics must be designed produced. This study focuses on possibility of developing an aluminium composite using agro-waste as reinforcement preference to other chemicals materials. The morphological ana...

Corrosion is well known to reduce the structural integrity of aluminium alloy aircraft components. In addition, it can cause early fatigue failures in components in which fatigue is not considered to be a life limiting factor. This is because corrosion damage, such as corrosion pits, is up to 100 times the size of the inclusions intrinsic in most aerospace aluminium alloys. The trailing edge fl...

Background: AA2519-T87 is a new armour grade aluminium alloy employed in the fabrication of light combat military vehicles. Joining of this material using fusion welding processes, results in the formation of solidification defects like porosity, alloy segregation and hot cracking. In order to overcome the solidification related problems, solid state welding processes such as friction stir weld...
