Nanometers Formation Model of Iron (Fe) and Magnesium (Mg) on Graphene Nano Sheets

Abstract

: An experimental research is being conducted on the joining of dissimilar materials of grey cast iron to low carbon steel utilizing diffusion bonding method. Diffusion bonding process operates on the principle of solid-state diffusion, wherein the atoms of two solid, metallic surfaces intersperse themselves over time, moving an atomic mass form or diffusion through the lattice of a crystalline solid. Upon producing of the diffusion couples through diffusion bonding, the bonds are subjected to SEM (Scanning Electron Microscopy), EPMA (Electron Probe Micro Analyzer), XRD (X-Ray Diffraction), EDS/EDX (Energy Dispersive X-Ray Spectroscopy), WDX’s (Wavelength-dispersive X-ray spectroscopy) micro-structural analysis and mechanical properties examination. Subsequent investigation is to be carried out to establish the diffusion mechanism, inter-diffusion coefficients and activation energy of the diffusion system. To study the optimum conditions that produce excellent and ultimate bond, various bonding parameters and variables are taken into consideration. This paper describes the research progress undertaken to date, explaining the materials involved, equipment, method and preliminary as well as current results on microstructure analysis, tensile test and micro-hardness test.
