Aluminium metal matrix composites are widely used in engineering applications, specially automobile, aerospace, marine and mineral processing industries owing to their improved wear properties compared to conventional monolithic aluminium alloys. Presently hybrid composites plays vital role in engineering application. The researchers who developed composites, were subjected to many characterisa...

Hierarchically structured aluminium oxide was hydrothermally synthesized with carbamide as a precipitator. Raman spectroscopy, SEM spectroscopy, and X-ray phase analysis were used to investigate morphology and parameters of porously structured aluminium oxide as influenced upon by concentration of reactive solution, excessive portions of precipitator, and the counterion type. Differing mechanis...

Electron Beam Melting (EBM R ©) is a near-net-shape additive manufacturing technology developed by Arcam AB, where Ti-6Al-4V alloy powder is commonly used to manufacture medical implants and components for the aerospace industry. Although Arcam has developed special specifications of some parameters for the powders, the powders from different manufacturers do not behave in the same way in the E...

Light weight materials coupled to the need for cost-effective processing have combined to create a significant opportunity for aluminium powder metallurgy as its increasing interest. Aluminium alloy (AA 2219) metal matrix composite reinforced with multi walled carbon nanotube (MWCNT) produced by powder metallurgy (P/M) technique was analysed and CNTs dispersion were traced. The micro hardness a...

In this study, mechanically alloyed Al 2024 powder is densified by conventional sintering and by equal channel angular pressing (ECAP) with and without back pressure. The powder was encapsulated in an aluminium can for consolidation through ECAP. The properties obtained in the compacts by conventional sintering route and by ECAP are compared. The effect of conventional sintering and ECAP on con...

A validation study in order to evaluate the efficiency of the inductively coupled plasma optical emission spectrometry (ICP-OES) in the analysis of minor elements (Manganese, Chromium, Copper, Iron and Titanium) in aluminium alloys was carried out. Aluminium casting samples were obtained from addition to aluminium baths of compressed powder compacts of each alloying element and aluminium (minit...

Additive Manufacturing offers geometric freedom excellently suited for topology optimized light weight designs. Ideally these should be produced from materials of high strength to weight ratio such as aluminium-copper alloys. Yet these are considered unsuitable for welding. With Laser Beam Melting of Metals in powder bed (LBM), the only class of aluminium alloys widely processed is that of alum...

A structural refinement of a natural sample of a Co-bearing mansfieldite, AlAsO(4)·2H(2)O [aluminium orthoarsenate(V) dihydrate], has been performed based on synchrotron powder diffraction data, with 5% of the octa-hedral Al sites replaced by Co. Mansfieldite is the aluminium analogue and an isotype of the mineral scorodite (FeAsO(4)·2H(2)O), with which it forms a solid solution. The framework ...

the aim of this project is to fabricated an aluminium-copper bimetal through the fusion method and examine its performance. an aluminium-copper-aluminium bimetal was built by the laser cladding method. the laser power as well as the annealing time effects on its interfacial properties of the bonding’s formed through the laser cladding were investigated. to fabricate the multilayer bimetal, the ...
