Abstract

We have presented four applications of Image Analysis to material science. The first one is on a yarn composite SiC where we want to know the relative proportion of matrix, fibers, porosity and the size of the fibers. The results are used to estimate mechanical properties of the composite.

The second one is to measure the residual porosity after a laser shock on powder metallurgy steel. The knowledge of the depth of the affected zone is necessary to optimise the laser treatment.

The third one uses Fourier transformation to analyse plastic deformation on grains. Values are obtained from Fourier transform images.

The last one is to make measurements of the length of cracks on fracture sample, to separate intergranular and transgranular character of a fracture surface.
