辐照腐蚀专题讨论会 Title:CorrosionbyIrradiation:ASpecialDiscussiononthe Phenomenon Introduction: Corrosionisanaturalprocessthatgraduallydeteriorates materials,oftenresultinginsignificanteconomicloss,safety hazards,andenvironmentalconcerns.Whilecorrosionistypically associatedwithchemicalreactions,recentstudiesareshedding lightonalessexploredformofcorrosion-irradiation-induced corrosion.Thisconditionoccurswhenmaterialsareexposedto ionizingradiation,causingaccelerateddegradation.Inthispaper, weaimtodiscussthephenomenonofirradiation-induced corrosion,itsmechanisms,impact,andpotentialmitigation strategies. 1.UnderstandingIrradiation-InducedCorrosion: 1.1DefinitionandScope: Irradiation-inducedcorrosionreferstothecorrosionprocess resultingfromtheinteractionofmaterialswithionizingradiation, suchasgammarays,X-rays,orenergeticparticles.Thecorrosion iscausedbyradiation-inducedeffectsonatomicstructures, includingdisplacementofatoms,creationofdefects,and generationofnewchemicalspecies. 1.2MechanismsofIrradiation-InducedCorrosion: Themechanismsofirradiation-inducedcorrosioninvolve severalcomplexprocesses,includingradiationdamage,material activation,andchemicalreactionsinitiatedoracceleratedbythe radiation.Defectformation,grainboundarymigration, segregation,andatomicdiffusionplaycriticalrolesinthe corrosionprocess. 2.EffectsandConsequencesofIrradiation-InducedCorrosion: 2.1MaterialsAffected: Irradiation-inducedcorrosioncanimpactawiderangeof materials,includingmetals,polymers,ceramics,andcomposites.
