Abstract

The spatial distribution of pores in lotus-type porous magnesium has been studied with the second-order characteristics and the nearest-neighbour distance distribution by using statistical analysis methods. The results show that the spatial distribution of pores is short-range ordered. On the basis of the analysis, two structural indices deduced from the variance of nearest-neighbour distance distribution and the standard deviation of local porosity from Dirichlet tessellations were proposed for quantitatively characterizing the pore distribution.
