Abstract：

The　influence　of　temperature　on　hydrogen　diffusion　and　hydrogen　embrittlement　of　X80　steel　was　studied　using　electrochemical　hydrogen　charging.　The　hydrogen　diffusion　and　subsurface　hydrogen　concentration　in　the　steel　increased　with　increasing　the　temperature.　Macro　slow　strain　rate　tensile　tests　and　microstructural　analysis　were　performed　to　unveil　the　dependence　of　hydrogen-induced　embrittlement　susceptibility　on　temperature,　which　suggested　a　temperature　threshold　THE,　max　of　315　K.　The　demonstration　of　THE,　max　would　be　crucial　for　determining　test　temperatures　of　hydrogen-related　engineering　material　applications.　©　2023　Elsevier　Ltd
