Dr. Ajit Mishra and I have organized the upcoming TEG 407X (STG 60) Mechanisms of localized corrosion in Memoriam of Professor José Galvele (March 1937 - August 2011). The year 2016 marked the 40th anniversary of Prof. Galvele’s seminal “Transport Processes and the Mechanism of Pitting of Metals” publication. Our goal for the symposium was to bring the best of industry and academia under one roof. We will be honored by the presence of distinguished guest speakers from both industry and academia. A list of lecturers and scope of their talks is presented below.
What is the localized corrosion resistance of the Nickel alloy 718 (UNS N07718) in oxidizing chloride containing environments like seawater? This articles gives some clues.
SCC of AZ31B alloy was studied in NaCl solutions at different potentials and chloride concentrations using the slow strain rate technique. A combination of pre-exposure tests followed by immediate straining or straining after a dry air exposure delay helped to weight the relative importance of anodic damage accumulation versus increased hydrogen charging during open-circuit potential pre-exposure. The dependence of ductility with pre-exposure time and the fracture surface of embrittled samples suggest that hydrogen embrittlement of AZ31B was controlled by hydrogen diffusion.
