Aluminium is one of the widely used metals in industrial sector owing to its specific features and its commercial production started in late 19th century. In its natural form it is combined with oxygen and other elements and is the third most abundant metal in the earth’s crust. It can be machined easily and has a Face Centred Cubic (FCC) structure. Aluminium alloys are an attractive alternative to ferrous materials for tribological applications due to their low density and high thermal conductivity. The microstructure of aluminium alloys can be modified and mechanical properties can be improved by alloying, cold working and heat treatment. The present work mainly focuses on the study of the effect of variation in composition on the wear characteristics and compressive strength of aluminium alloy Al6463 by varying the compositions of the two major alloying elements, Magnesium (Mg) and Silicon (Si) in the alloy. Four specimens of the aluminium alloy Al6463 are prepared each for Magnesium composition varying b/w (0.5 to 0.875%) and Silicon composition varying b/w (0.2 to 0.575%). Wear and compression tests were carried out as per ASTM standard. The results of the wear test indicate that the least wear rate was obtained for specimens of 0.750% Mg and 0.575% Si composition of the alloy Al6463 at a higher load of 1.5 kg. Also, the compression test results indicate that the specimens with 0.750% Mg and 0.575% Si compositions of the alloy Al6463 exhibit better compressive strength.

“…The impact factors, considered in the works, apply only to the alloys, based on the Al-Be system. Paper [10] considers alloying of aluminum alloy A 6063 by titanium carbide, due to an increase in the amount of which during alloying, impact ductility and elongation of composites decreased up to 31 % and 35 % respectively. However, as the authors note, density, hardness and breaking strength of the alloys increased up to 7.8 %, 20 %, and 19.55 % respectively.…”

“…Among these, particle reinforced aluminium matrix composites are used widely. Here ceramic particles like carbide (SiC, B 4 C, TiC etc), oxides (Al 2 O 3 , MgO, ZrSiO 4 , ZrO 2 etc), borides (TiB 2 , AlB 2 etc and nitrides-BN, AlN etc) are reinforced with aluminium melt [15][16][17][18][19][20][21][22]. Addition of these reinforcement improves the mechanical and tribological properties of aluminium and thus makes it suitable for numerous fields of application including automobile, aerospace, defence, mineral processing, sports goods etc.…”

This study focuses on fabricating aluminium hybrid metal matrix composites reinforced with ecofriendly agro waste, cow dung ash and boron carbide by two stage stir casting. Weight percentage of cow dung ash and boron carbide were added in ratios of 2.5:7.5, 5:5, and 7.5:2.5. The effects on mechanical properties like hardness, tensile strength, impact strength, flexural strength and wear behaviour were studied. SEM and EDX analysis were employed to study the fracture mechanism for tensile, impact and wear specimens. Optical microstructure images reveal uniform distribution of particles and XRD analysis confirms the presence of reinforcements. Increasing CDA particles has reduced the density of the hybrid composite up to 8%. A maximum increase in hardness, tensile strength and wear resistance was up to 30%, 56% and 56% respectively, and then a slight decrease in impact was found in increasing the CDA particles. Dimples, transgranular cleavage facets, cracks and micro ploughing, micro cuttings are revealed from the fractured specimens of tensile, impact and wear respectively.
