In this work, aluminium composites have been evaluated in terms of their characteristics and behaviour. Stirring metallics a specific quantity ceramic-derived silicon nitride resulted AA6061 (Si3N4). The mechanical, corrosion, tribological properties were investigated. Tensile, hardness improved with constant weight percent ceramic advanced metallic fortification. the composite has decreased we...

Original scientific paper The paper deals with the effect of roughness, residual stresses and pitting corrosion on different shot peened (SP) ENAW 7075 aluminium alloy in different states. Suitable residual stress profile increases the applicability and life cycle of mechanical parts, treated by shot peening. Pitting corrosion has a major influence on aging of structural elements made of high s...

The present requirement of automobile industry is seeking lightweight material that satisfices the technical and technological requirements with better mechanical and tribological characteristics.  Aluminium matrix composite ( AMC ) materials meet the requirements of the modern demands. AMCs are used in automotive applications as engine cylinders, pistons, disc and drum brakes. This paper inves...

Laser shock peening (LSP) can introduce a compressive stress profile for improving the materials’ surface mechanic properties. 6065 Aluminium alloy is introduced recently in the aeronautic components. The surface performances of the components are related directly to the surface activity and surface corrosion properties which are influenced by the near-surface stress gradient. So, the determina...

This paper presents positron lifetime studies of the subsurface region of AK12 aluminium alloy and Al2O3-particle-reinforced AK12 aluminium alloy composite after sliding against steel in the pin-on-disc machine. The defect depth profile detected in the AK12 alloy extended up to 300 μm but for the composite AK12 the range of this profile was significantly shortened to less than ∼ 90 μm. The posi...

For additive manufacturing such as laser powder bed fusion (LPBF), commercial aluminum alloy (AA) 6061 is typically considered unsuitable due to formation of solidification cracking and/or excessive porosity. In this study, improve buildability/printability AA6061, 1 wt% Zr was alloyed produce Zr-modified AA6061 by LPBF. Powders unmodified and were produced gas atomization, utilized a feed-stoc...

The reaction of aluminium(III) with Hydroxynaphtol Blue (HNB) in aqueous media at apparent pH 5.5 results in a red complex that is stable for at least 4 hr. Beer's Law is obeyed up to 1.6 microg/ml of aluminium(III) with an apparent molar absorptivity of 1.66 x 10(4) l.mol(-1). cm(-1) at 569 nm. This paper proposes procedures for aluminium(III) determination by ordinary and first-derivative spe...

In this investigation ‚the fracture toughness of A356 containing15%SiC composite was studied. Al/SiC composites have been considered because of their mechanical and erosion properties .Low fracture toughness in Al/SiC as compared with Aluminium alloys is one of its disadvantage. In this study at first A356 alloy was melted in a smelting electrical furnace then poured into the mould. A356-15% Si...
