The Fatigue Behavior of High Strength Aluminum Alloys under Cathodic Charging Conditions.

Abstract

Cathodic charging of cyclically stressed high aluminum alloys results in large decreases in fatigue resistance. These observations, coupled with tensile test experiments which show interrupted flow, suggest that hydrogen, interacting with dislocations, effectively reduces plasticity in the region near the crack tip.
