Abstract

In this study Al-Al₃Ti-SiC and Al-Al₃Ti-Al₄C₃ metal matrix composites (MMCs), processed by atomization/co-deposition (AD) and mechanical alloying (MA) respectively, were investigated before and after hydrogen exposition. The results show that under severe conditions, such as exposure to NaCl solutions at cathodic charging conditions, initial crack propagation in the MMCs occurs without any applied stress. The interaction between hydrogen and interfaces, such as grain boundaries and phase boundaries induced fracture on these defects; however, it was found that boundaries show different behaviors depending on their nature.
