Vellore Institute of Technology-Subham Jaiswal, Govindasamy Rajamurugan, Prabu Krishnasamy, Yashwardhan Shaswat, Mishra Kaushik
Published 2019-10-11 by SAE International in United States
Various research regarding new types of fabrication and modifications of Aluminium alloy to improve the existing properties are going on. The wide range application of aluminium alloy is in aerospace and Automobile Industries. The demand for this material improved by mechanical properties with little to zero increment in weight. The current work is based on the fabrication of hybrid aluminium metal matrix composites with the addition of TiC (Titanium Carbide) and Al2O3 (Aluminium Oxide) reinforcement particle using stir casting technique. Three types of hybrid composite samples were prepared based on the weight percentage 5% Al2O3+0% TiC (sample-1), 8% Al2O3 + 12% TiC (sample-2), 20% Al2O3+15% TiC (sample-3). The objective of the study is to analyze the mechanical and corrosion properties of the hybrid composite with the influence of the reinforcement and varying the weight fraction of the particles. Overall, It is observed that a gradual increase in the hardness value in sample-1(83 BHN), Sample-2 (88 BHN) and sample-3 (96 BHN). This trend can be explained by the particulate strengthening of TiC over the soft ductile…

Published 2019-10-11 by SAE International in United States
The connecting rod was manufactured by forging process for enhancing high tensile and compressive load so that it was followed by the machining process and suite the IC engine as a part of the component. The main intern of our proposed work is to manufacture a two set of composites specimen of A356 alloy with reinforcement of 5 wt.% silicon carbide and 10 wt.% flyash processed through two different techniques like stir casting and stir cum squeeze casting route and obtain better mechanical properties. Further, the same properties were taken for modeling and analysing of the developed connecting rod model. Due to the commercial demand, the hybrid composite materials take a vigorous role in the analysis part of the connecting rod model. The FEA analysis is done on the connecting rod for a180cc engine by using Ansys 18.1. The static analysis is done by considering four different cases by altering material library property. The output parameter such as total deformation, Von Mises stress, and maximum equivalent elastic strain are taken in each condition. The analysed…

Composites materials are substituting constituents for traditional materials due to their remarkable properties, and the addition of nanoparticles gives a new development in the material domain. The nanoparticles influence on fabrication and machinability investigation study is essential as the composites to be used in applications like automotive and aerospace. The current study investigates the machinability characteristics of Al2219 based metal composites reinforced with nanoparticles of SiN/MoS2. Al2219- reinforcements (SiN and MoS2) composites are fabricated by the method of stir casting. Four different compositions (Al2219/SiN (2 wt% and 4 wt%), , Al2219/2 wt.% SiN/ 2 wt.% MoS2, Al2219/2 wt.% MoS2) are fabricated by varying the different weight percentages of nanoparticles reinforcements. An attempt is made to study the investigation analysis of force, surface roughness, and tool wear using CNC machine lathe to consider the effect of cutting speed, cutting depth, and samples. The machinability test is carried out, and the performance is compared. Addition of 2 wt% of SiN in Al2219 is to increase the hardness of nearly about 21%, 14%, 40% compared to that of…

A Comparative Study on Microstructures and Mechanical Properties of Al-GNPs Composites Fabricated by Casting Method

Sree Vidyanikethan Engineering College-Bhanu Prakash Palampalle, Krishnamachary Pattipati Chinna, Binoj Joseph Selvi
Published 2019-10-11 by SAE International in United States
This paper describes an investigation on microstructures as well as mechanical properties of pure aluminium graphene nano platelets (GNPs) metal matrix composites prepared via novel based stir casting technique combined with ultrasonic treatment. The proportion of graphene changes from 0.5 to 2.0 wt. % in aluminium with 99% purity. The investigations on composites revealed that Al with combination of 1.0 % graphene composite showcased enhanced mechanical properties with 48.49 % (~49%) increase in tensile strength and 34.53 % (~35%) increase in micro hardness compared to test results of composites produced by traditional stir casting technique. FESEM analysis was done to examine the surface morphology of produced composite and fracture surface of tested composites where as XRD analysis was to inspect the phase analysis of produced composites. It reveals that, through cavitational effect there was a uniform distribution of graphene in aluminium matrix and composites were casted with less porosity due to which there is significant enhancement in mechanical properties compare to composites produced by stir casting technique
