CORROSION 2016: Mechanisms of Localized Corrosion Symposium – In Memoriam of Professor José R. Galvele

February 8, 2016 by Mariano Iannuzzi

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.

Hydrogen diffusion control during stress corrosion cracking of magnesium alloy AZ31B in chloride solutions – Abstract

November 26, 2013 by Mariano Iannuzzi

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.

Selecting corrosion resistant alloys for seawater applications

November 25, 2013 by Mariano Iannuzzi

This abstract has been submitted to the upcoming NACE International CORROSION/14 Research in Progress Session on Passivity and Localized Corrosion. By: Mariano Iannuzzi Coauthors: Mauricio Rincón-Ortiz (first author), Mariano Kappes, Martín A. Rodríguez, Ricardo Carranza, and Raúl Rebak. In the offshore oil and gas industry, materials selection philosophies are traditionally based on the International Standard Organization (ISO) 21457 […]
