Abstract
The present study aims at evaluating the shear and tensile behaviour of untreated and cryogenically treated aluminium-silicon carbide and aluminium graphite metal matrix composite. In this composite Al6061 is used as matrix material with varying Silicon carbide quantity from 2.5wt% to 10wt% and also varying the quantity of graphite from 1wt% to 4wt%. The composites used for this study were fabricated using stir casting technique. Electron dispersive X-ray spectroscopy and X-ray diffraction tests were carried out to know the composition and phase identification of the composite sample. Microstructure analysis was carried out to study the structure of the composites with and without cryogenic treatment.
Highlights
Composite materials have effectively submitted the customary materials in a few light weight and high quality applicants
Aluminium metal matrix composites generally utilized in high-tech structural and functional applications including defence, aerospace, automotive, and thermal management areas and sports
The Mg2Si and SiO2 are the products of reaction which shown as Mg and Si peaks in EDS graph after cryogenic treatment
Summary
Composite materials have effectively submitted the customary materials in a few light weight and high quality applicants. A composite material is a material system composed of two or more physically distinct phases, the properties of a composite as a whole are enhanced as compared with the properties its components. Composite material consists of two phases, primary phase and secondary phase. Matrix forms the primary phase within which secondary phase is imbedded. The embedment is known as reinforcement or secondary phase
