Abstract
In this paper,the internal microstructure deformation of open-cell
and closed-cell aluminum foams under compression was investigated
by using synchrotron radiation X-ray computed tomography (SR-CT)
technique and digital image analysis method. The reconstructed images
were obtained by using filtered back projection algorithm based on
the original images taken from SR-CT experiments. Several important
parameters including cross-section porosity,total porosity and cross-section
deformation were computed from the reconstructed images. The variation
of these parameters provided useful evolution information of internal
microstructure of aluminum foams under compression.
