摘要
Our research program seeks to understand the influence of hydrogen on steels for the hydrogen economy.The present paucity of affordable hydrogen-proof materials poses strong technological and economic barriers to the hydrogen economy.Our research seeks to understand the behaviour of medium-strength-steels.Our research includes: (i) understanding the hydrogen influence on steels using the linearly increasing stress test ( LIST) and fatigue tests for electrochemically charged specimens;( 2) evaluating the hydrogen fugacity equivalent to the electrochemical hydrogen charging,using ( i) electrolytic permeability experiments and ( ii) thermal desorption spectroscopy ( TDS).The approach for each is described.The theoretical underpinnings are explained.The first results are presented and the future research directions explained.
