Abstract
Mechanisms of hydrogen embrittlement in steels and other materials are described, and the evidence supporting various hypotheses, such as those based on hydride formation, hydrogen-enhanced decohesion, hydrogen-enhanced localised plasticity, adsorption-induced dislocation emission, and hydrogen-vacancy interactions, are summarised. The relative importance of these mechanisms for different fracture modes and materials are discussed based on detailed fractographic observations and critical experiments.
About the author
Dr. Stan Lynch is originally from Liverpool in England and completed his BSc and PhD degrees at the University of Manchester Institute of Science and Technology (UMIST) before emigrating to Australia in 1970 where he has since worked at the Australian Defence Science & Technology Organisation in Melbourne. He is also an Adjunct Research Associate in the Department of Materials Engineering at Monash University. He has been an associate editor of several journals including Acta and Scripta Materialia, Corrosion Reviews, and the ASM Journal of Failure Analysis and Prevention. Stan has over 40 years’ experience of research concerning environmentally assisted cracking, microstructure-property relationships (especially in Al alloys), and failure analysis, and has published over 100 papers on these topics. He has also presented numerous invited lectures on these subjects at international conferences and laboratories around the world.
