Abstract

The development of advanced air frames and propulsion systems has generated a great deal of research and development in the area of lightweight, high temperature intermetallic alloys. The present study characterizes the microstructures of spray atomized and co-deposited of spray atomized and codeposited metal matrix composites (MMCs) following hydrogen charging. The results show that, under severe conditions, such as exposure to NaCl solutions at cathodic charging conditions, initial crack propagation in Al-Ti/SiCp MMCs occurs without any applied stress. The phenomenology of hydrogen embrittlement and its possible mechanisms are discussed.
