    Defect Analysis of Dissimilar Steel Welded Joints of Martensitic Steel/Austenitic Steel in Power Station Boiler

      Graphical Abstract
      • Abstract
    • Some defects of dissimilar steel welded joints of martensitic steel/austenitic steel were enumerated, including hot cracks, early faliure due to overheating during the heat treatment,Ⅳ crack and δ-ferrite at the side of martensitic steel. The reasons were analysed and the preventive measures were put forward.
