Pore collapsed behavior of porous aluminum during compression process by using X-ray CT nondestructive observation

Abstract

Closed-cell porous aluminum is a multifunctional material with both lightweight and high energy absorption properties. These properties are considered to be governed by morphology of pores of porous aluminum. In this study, compression test was conducted in the X-ray CT system and deformation process of pores was nondestructively observed during compression. It was shown that deformation process of individual pore can be observed in this system.
