Effect of hydrogen on the mechanical behaviour of carbon-alloyed Fe3Al-based iron aluminides

[摘要] The effect of hydrogen on the mechanical behaviour of two carbon-alloyed iron aluminides was studied. Weakening of some carbideâ€�?�metal interfaces in the presence of hydrogen was indicated. The effect of cathodic hydrogen charging on the microstructure has also been addressed.
