Molten　salt　is　commonly　used　as　high-temperature　heat　transfer　and　thermal　energy　storage　(TES)　medium.　The　stress　corrosion　is　a　crucial　influence　factor　for　safety　operation　of　molten　salt　TES　system.　This　work　summary　the　methods　and　evaluation　parameters　of　molten　salt　stress　corrosion.　The　stress　corrosion　behavior　of　different　metal　alloys　in　various　kinds　of　molten　salts　is　compared　and　analyzed,　the　anode　dissolution　mechanism　and　hydrogen-induced　cracking　mechanism　of　stress　corrosion　are　summarized,　and　the　slip　dissolution　mechanism　and　oxide　film　cracking　mechanism　of　stress　corrosion　cracking　in　molten　salt　are　expounded　and　explored.　Furthermore,　the　influence　of　metal　alloy　microstructure　on　molten　salt　stress　corrosion　is　summarized,　the　relationship　between　the　addition　of　material　components　such　as　Ni,　Mo,　and　N　and　the　susceptibility　of　molten　salt　stress　corrosion　is　analyzed,　and　the　effects　of　molten　salt　impurities,　stress　and　temperature　changes　on　molten　salt　stress　corrosion　are　discussed.　The　corrosion　depth　is　positively　correlated　with　corrosion　time,　molten　salt　temperature,　and　stress　on　the　metal　alloy.　Additionally,　the　strategies　to　inhibit　and　alleviate　stress　corrosion　in　metal　alloys　are　presented,　such　as　coating,　optimizing　the　alloy　composition　of　materials,　etc.　Finally,　the　further　research　direction　of　stress　corrosion　in　molten　salt　is　proposed,　which　is　of　great　significance　for　selecting　suitable　metal　alloy　materials　for　molten　salt　TES　system.　©　2024
