Preparation of Al6061-SiC with Neem Leaf Ash in AMMC’s by Using Stir Casting Method and Evaluation of Mechanical, Wear Properties and Investigation on Microstructures

Abstract

Aluminum Metal Matrix Composites (AMMCs) are promising materials for advanced structural, aviation, aerospace, marine, defense applications, automotive and other related sectors because of their excellent combination of properties. The AMMCs is fabricated by using stir casting method, which is the simplest way of fabricating a material. In this paper aluminium alloy 6061 is been reinforced with SiC along with fly ash and neem leaf ash. The three samples have been fabricated they are Sample1 (Al85%+SiC15%), Sample2 (Al 85%+SiC5%+FlyAsh10%) & Sample3 (Al85% +SiC5%+ Neem leaf ash10%). After fabricating this three sample the following test are conducted like Hardness test, Microstructure Test, Friction and Wear Test. The wettability of SiC and Neem leaf ash particles in the matrix was improved by adding them. The optical and scanning electron micrographs showed a homogeneous dispersion of composition material. The result shows that the Sample-3 (Al80% +SiC10%+ Neem leaf ash10%) shows improvement in mechanical properties like hardness, the wear properties has been reduced and their Micro structural characterization clearly shows uniform distribution of SiC and Neem Leaf ash in the composition.

Experimental and Statistical Analysis of Effect of Si Modification and Grain Refinement on Tensile Properties of A356 Alloy

“…The relationship between the bifilm index and mechanical properties can be seen clearly in Figure 3. As the bifilm index was increased, the mechanical properties decreased [58,[71][72][73][74][75][76]. Similar results were reported previously by Caceres [69].…”

Assessment of Mechanical and Tribological Behavior of AA6061 Reinforced with B4C and Gr Hybrid Metal Matrix Composites

“…The mechanical and tribological behavior of AA7075-SiC with neem leaf ashes (containing high carbon content) is also examined, where the WR decreases. At the same time, the material strength increases due to the presence of silicon carbide [12]. The microstructure of AA 7075 undergoes significant changes when carbon nanoparticles are added, resulting in notable improvements in mechanical characteristics such as tensile and compression strength [13].…”
