6061 Aluminium Alloy

This paper deals with the 7005 aluminium alloy characterization which has similar physical properties to 6061 aluminium alloy, depending on the temper, may be slightly stronger. To increase their mechanical and physical properties silicon carbide had been introduced in it as reinforcement. Based on mass three different compositional were made and mixed thoroughly, and cast. Stir casting method is used for casting proportioned alloys. Heat treatment process is carried out after casting the alloy is mixed in the three proper compositions. Mechanical properties like hardness, Tensile strength and impact strength were conducted and analyzed. Properties can be altered in a better way using silicon carbide as an reinforcement in aluminium-7005.

Abstract      In this investigation, Al2O3 nano material of 50nm particles size were added to the 6061 Al aluminium alloy by using the stir casting technique to fabricate the nanocomposite of 10wt% Al2O3. The experimental results observed that the addition of 10wt% Al2O3 improved the fatigue life and strength of constant and cumulative fatigue. Comparison between the S-N curves behaviour of metal matrix (AA6061) and the nanocomposite 10wt% Al2O3 has been made. The comparison revealed that 12.8% enhancement in fatigue strength at 107cycles due to 10wt% nano reinforcement. Also cumulative fatigue life of 10wt% nanocomposite was found to be increased by 33.37% and 39.58% for low-high and high-low loading sequences, respectively, compared to the metal-matrix cumulative life. Keywords: Al2O3 nanoparticles, AA6061/10wt%, constant and cumulative fatigue, MMCs.

The Impact

Mechanical properties (impact, hardness and tensile strength) characterization of samples containing homogenous mixtures of Al 6063 matrix and varying amount of silver nanoparticles mixed with calcium carbonate at 2, 4, 6% weight fractions, respectively, produced by method of stir casting were carried out. Measurement of impact energy, hardness and tensile strength of the produced samples at 24℃ (ambient) temperature was done by Charpy impact, Brinell hardness and universal tensile testing machine in accordance to ASTM E23, E384 and E8/E8M-13M, respectively. The magnitude of impact and hardness increased evidently with increase in percentage weight fraction of the AgNPs. The refined samples were examined under an optical microscope. The fracture surfaces of the impact test samples were further examined by scanning electron microscopy. There is an increase in tensile strength, elongation and modulus of elasticity of Al-AgNP composites compared to as-cast aluminium alloy. The use of stir-casting technique influences the homogeneity and microstructure of the composites positively. It is concluded that Al-silver nanocomposites possess better qualities in hardness and strength and can replace conventional aluminium alloy in terms of performance and longer life in industrial application.

Aluminium alloy(A 356) has improved properties such as tension and elongation butit is decreased in hardness property compared to ceramics and therefore silicon carbideparticle (SiCp) is added with aluminium alloy to increase its hardness. Silicon Carbideparticle is abrasive and hence having poor interfacial bonding between ceramics andaluminium, so that the surface of the ceramics is coated with Multi Wall Carbon Nano Tubes(MWCNT). In this paper 10% of SiCp is taken for the experiment and coated with 1.5%, 2%,2.5% of MWCNT and this coated SiCp mixed with molten A 356 using stir casting method.The prepared castings were mechanically tested using Universal Testing Machine (UTM),Vickers hardness Testing Machine, Impact Testing Machine and Optical Microscope andtheir mechanical properties and morphological characteristics were studied

In this modern world, composites are used in almost all fields due to their attractive mechanical and technological properties. They are believed to be fast replacing metal alloys thanks to their adaptability, flexibility, formability, and machinability. The present study deals with the comparative evaluation of mechanical properties between various aluminium alloy composites reinforced with boron carbide and rice husk ash at different proportions and their optimization through ranking of alternatives using TOPSIS. The composite specimens are fabricated by a liquid metallurgy technique called stir casting. The sample specimens are prepared by varying the percentage of reinforcements as per volume-based ratio with respect to the aluminium alloy Al 6061. The evaluation of mechanical properties indicates the improvement in tensile strength, hardness, impact energy, and corrosion resistance for different composite combinations compared to that of individual alloy. Finally, the best possible combination is identified among the given set of various proportions by optimization using TOPSIS.

Solid Glass Microspheres (SGM) in the range of 10–20 vol. % were used as reinforcement for making aluminium alloy metal matrix composite having density 2.66–2.68 gm/cc using stir-casting technique. Aluminium alloys are not new for synthesizing Metal Matrix Composites (MMC’s), as they have already established their exceptional ability to sketch out the material for required properties where high strength is expected from a low density material. This has made them one of the widely used materials for aeronautics and marine applications where strength and weight are among the major governing factors for the suitability of any material. So, an effort is made to enhance the strength of aluminium alloy LM13 without affecting its lightness, by reinforcing it with Solid Glass Microspheres (SGM). This synthesized composite, is characterized in terms of its density and compressive deformation behaviour. It was observed that the developed composite behaves somewhat like a high strength aluminium foam under compressive deformation as exhibited in the stress–strain curves. The results of density evaluation and compression showed a substantial enhancement in the compressive strength of the developed composite with a considerably low change in density.

Stir casting method was used to manufacture these aluminium alloy LM13 and SGM particulate composite with 10 v%, 15 v% and 20 v% of reinforcement. Based on ASTM benchmarks, the composite samples were prepared and tested, and the results obtained were then analysed. A notable improvement was perceived in the strength of tensile and compressive capacities of the developed metal matrix composites (MMC).
