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...

A base aluminium-silicon alloy AlSi25Cu5Cr was used to investigate the possibility of alloying aluminium alloys with hard-to-melt elements. The elements Co, Cr and Mo were introduced into melt using metal powder from a hard-melting dental cobalt-chromium-molybdenum alloy. packed in foil studied at temperature 810º C. After mechanical stirring melt, it stood for 30 min. temperature, raised 850º ...

The connecting rod is one of the most important moving components in an internal combustion engine. present work determined possibility using aluminium alloy 7075 material to design and manufacture a for weight optimisation without losing strength rod. It considered modal thermal analyses investigate suitability design. parameters that were under analysis were: total deformation, natural freque...

This study describes a model (MIKADO) to analyse options to reduce the environmental impact of aluminium die casting. This model will take a company perspective, so that it can be used as a decision-support tool for the environmental management of a plant. MIKADO can be used to perform scenario analyses to analyse the impact on the environment of different strategies, while taking into account ...

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...

Aluminium alloy composites have been extensively investigated for use in tribo-contact applications, however little detailed literature exists on the sub-surface microstructural evolution as a result of lubricated sliding wear. In this study two un-reinforced alloys (2124 & 5056) and identical alloy composites, reinforced with 15vol.% MoSi2 intermetallic particles were produced by a powder meta...

Metallic lattice truss structures are usually made by perforating a metal sheet with a periodic diamond pattern followed by folding at node rows to create a plate of 3D interconnected trusses. For low relative density lattices, the initial sheet material is inefficiently utilized, and the node area is small raising concerns about node bond robustness under shear or tensile loading. Here, we exp...

Nanoindentation has been used to study the hardness changes produced by scratching of aluminium alloy AA2024, with and without a clad layer of pure aluminium. The hardness was mapped around scratches made with diamond tools of different profiles. One tool produced significant plastic damage with associated hardening at the scratch root, whilst the other produced a ‘cleaner’ cut with no hardenin...
