Systematic Study of the Effect of Sensitization on Corrosion Fatigue of Aluminum-Magnesium Alloy used in Naval applications
Abstract
Funds are provided to study the effect of sensitization on Al-Mg alloy corrosion fatigue (CF) as a function of the fatigue loading frequency (f), maximum stress intensity, applied electrochemical potential, and sensitization utilizing high resolution fracture mechanics experimentation in naval relevant environments. The concept of experimental approach to study corrosion fatigue at low frequency typically seen in naval services is a very innovative and novel idea, since most of sensitization of Al-Mg alloy studies to date have been primarily focused on intergranular stress corrosion cracking (IGSCC). Therefore, the goal of this work is to bridge the gap in the fundamental understanding of the better-understood effects of Al-Mg alloy sensitization on IGSCC, and CF, where critical and systematic studies are lacking.
