Aluminium-Magnesium (Al-Mg) alloy extensively use in automotive, aerospace, designer furniture, etc. due to lightweight, anti-corrosive and easy processing methodology. In these applications, Al-Mg alloy suffered complex stress conditions (such as multi-axial tensile deformations) during extremely high external tensile/compressive load at atomic length scale. Therefore, we have studied multi-axial (uni-, bi- and tri-axial) tensile deformation of Aluminium - Magnesium alloys by molecular dynamics simulation. Pure Al and Al-Mg alloys exhibit highly brittle failure during tri-axial tensile deformation compared to uni- and bi-axial tensile deformations. The evolutions of nano-voids in pure Al and Al-Mg alloy have observed during tri-axial deformations. The Solvent Accessible Surface Area (S) and solid volume of nano-pores (V−Vs) have estimated of the characterization of nano-porous structure of pure Al and Al-Mg alloy during multi-axial tensile deformations. The dimension-less aspect ratio has been defined by View the MathML source, which is able to distinguish the growth and coalescence of nano-voids during multi-axial tensile deformation of metals and alloys with very accurately. We believe that these new findings will increase the understanding for the characterization of nano-voids in metallic materials.
