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...

carbon nano-tube (cnt) reinforced metal matrix nano-composites have attracted a great deal of attention in recent years due to the outstanding physical and mechanical properties of cnts. however, utilizing cnt as reinforcement for alloy matrixes has not been studies systematically and is still a challenging issue. in the present study, cu80fe20/10cnt nanocomposite was synthesized by mechanical ...

in this paper, an optimization method for both weight and displacement of composite blades is presented. in   order to hold issues such as aerodynamics and acoustic unchanged, airfoil shape during optimization process remained constant. to achieve the ultimate goal, only blade lamination was changed. in order to achieve minimum weight for each part of the structure, the lowest layers are foreca...

Abstract Composite metal foams are hybrid structures with the main advantages of high specific strength and mechanical energy absorption associated low density. In course our research, we successfully manufactured functional EN AC-44200 matrix filled lightweight expanded clay aggregate particles (LECAPs) in AW-6060 alloy tubes a diameter 50 mm wall thickness 5 mm. Manufacturing was performed by...

Experimental analysis of conventional turning (CT) and ultrasonically assisted (UAT) two varieties particulate SiC infused aluminium metal matrix composite (217XG, 225XE) is carried out. The results indicate the amount tangential cutting force reduction in UAT compared to CT increased at lower speed higher depth-of-cut. using carbide tools reduced average forces by 60.5%, 29.5% for 217XG 225XE,...

Abstract Aluminium matrix composites have gained interest recently because they are more efficient, lighter, and less expensive. The purpose of this current study was to examine the effects various casting operating conditions, including stirring temperature, time, speed, on process. Determining optimum processing parameters achieve significant outcomes could be most daunting problem while a sp...

A kind of environmental friendly novel composite flocculants which are used to treat raw water is prepared. It is made with chitosan (CS), iron modified polyaluminium chloride (CF-PAC) and modified montmorillonite on the principle of “the combination of organic and inorganic”. Under the optimum best compound formula and flocculation process, the turbidity of the waste water reduced by 0.62%, th...

Abstract In this study, four different combinations of aluminium metal matrix composites (AMCs) were produced using a computerized stir casting process. The feasibility car Scrap Aluminium Engine Head (SAEH) as material, Fresh Alumina Catalyst (FAC) and Spent (SAC) from petrochemical industries reinforcement material investigated. physical mechanical properties the cast samples tested through d...
