Study of metallic-ceramic composite foams with application of the computer tomograph

Abstract

The paper presents the study of the metallic-ceramic composite foams (the AlSi9 matrix, the SiC reinforcement) with application of the computer microtomograph. The morphology of these materials was also described in the paper, as well as generation of the three-dimensional models of the entire samples of foam. Additionally, quantitative image analysis was performed and the porosity of the test samples (with 3D analysis) and pore size distribution in the tested foams with different densities (with 2D analysis) was determined.
