Damage behaviour in different micro-regions of P92 steel weldment under sequential low cycle fatigue and creep loading
Engineering Fracture Mechanics(2021)
摘要
•Mechanical properties and microstructure of weldments were quantitatively evaluated.•The ICHAZ and adjacent regions exhibit the most sensitivity to fatigue loading.•The correlation between the micro-region properties and microstructure was clarified.
