This paper presents the characterization of A356 composite reinforced with fly ash and basalt ash produced by stir casting method. Aluminium metal matrix composites (AMC) are used in wide variety of applications such as structural, aerospace, marine, automotive etc. Stir casting is cost effective manufacturing process and it is useful to enhance the attractive properties of AMCs. Three sets of hybrid AMC are prepared by varying the weight fraction of the reinforcements (3% basalt + 7% fly ash, 5% basalt + 5% fly, 7% basalt + 3% fly ash). The effect of reinforcements on the mechanical properties of the hybrid composites such as hardness, tensile, compressive and impact strength were studied. The obtained results reveal that tensile, compressive and impact strength was increased when weight fraction of fly ash increased, whereas the hardness increases when weight fraction of the basalt ash increased. Microscopic study reveals the dispersion of the reinforcements in the matrix.

The Cost

Aluminium matrix composites (AMCs) having more than one reinforcement (hybrid AMCs) found enlarged use due to better strength, high thermal stability and wear resistance properties and can be a substitute for single reinforced AMCs .The effect of varying ball milled (BM) B4C/Si3N4 particles on the microstructure of as cast AA6082 and mechanical properties of AA6082 alloy hybrid composites produced by combined ball milling and conventional stir casting method have been reported. The combined reinforcement of BM B4C/Si3N4 particles were varied from 0-9 % in a step of 3. The wettability of B4C/Si3N4 into the aluminium melt has been increased by ball milling the boron carbide with silicon nitride powder, so that combined reinforcement of B4C/Si3N4 neither float nor sink in the aluminium melt. The investigated result showed that addition of combined reinforcement of BM B4C/Si3N4 increased Hardness and Ultimate tensile strength at the cost of reduction in percentage elongation.

Porosity Level

Al-Si-Mg reinforced with Al2O3 nano particles have been made by stir casting method. The vortex produced by stirrer is to distribute the Al2O3 nano particles in the molten aluminium. The volume fraction of Al2O3 nano particles was varied from 0.5, 1, 2, 3, to 5 Vf%, while the addition of magnesium was 3 Vf% as wetting agent to improve the wettability between Al2O3 nano particle and Al-Si-Mg matrix. The effect of Al2O3 on characteristic of Al-Si-Mg composites was studied. It is found that the presence of Al2O3nano particle led to significant improve in mechanical properties, especially at addition of 0.5 Vf% Al2O3. The ultimate tensile strength reached to 154 MPa with 10.24 % elongation, while the hardness reached to 37.7 HRB followed by decrement in wear rate. The porosity level tend to increase with increasing of Al2O3 and caused decrement in mechanical properties.
