Tri-axial Tensile Deformation Induced Nanoporous Structure of Aluminium: Estimation of Surface Area, Solid Volume and Dimensionless Aspect Ratio

Abstract

Nanoporous aluminium has great importance for large scale production of automobile and aerospace spare parts due to its light weight and non-corrosive nature. It is also suitable for various packaging application of edible things, electronic component, medicines etc. We have used tri-axial tensile deformation methodology to create a nano-porous structure of aluminium by using molecular dynamics simulation. The surface area and solid volume have been calculated to characterize the 3-D nanoporous structure of aluminium. We have quantitatively characterized the growth and coalescences of nanoporous by estimation of number of nanopore, nano-pore diameter and dimensionless aspect-ratio (surface area to volume ratio). High aspect ratio depicts the large number of tiny nanoporous in 3D-nanoporous structure of aluminium. We have found that the crystalline aluminium (at ambient condition) depict significantly lesser aspect ratio compared to amorphous state during triaxial tensile deformation. We believe that the results of this research will provide new understanding to researcher for design and characterization of nanoporous metals.
