Hydrogen can interact with any number of features commonly found in structural alloys, including point defects, dislocations, grain boundaries, particles, and voids. Many of these lattice defects can also act as nucleation centers for the formation of hydrides or second phases. The role of such trapping centers has been considered and modeled by a number of investigators. For example, it has become well-established that hydrogen introduced into aluminum alloys leads to significant embrittlement, particularly the embrittlement by cathodic charging of high strength 7000 series and 2000 series aluminum alloys. In the present study, the authors investigate the effects of hydrogen on an Al-Al{sub 3}Ti-Al{sub 4}C{sub 4} alloy having a fine-microstructure.
