Microstructural investigation of laser-shocked iron foils
Résumé
High-power laser shots were carried out on 100 microns thick iron foils. The present paper is devoted to the study of recovered fragments. Analysis of the fragments morphology shows the influence of shock pressure on the fragmentation process. Evaluation of the fragment-size distribution is performed in function of the laser power and the measured free surface velocity. The results highlight a clear evolution with laser power density.
