    Microstructure and Property in Simulated Heat-affected Zone of 06CuNiCrMoNb Steel

      Graphical Abstract
      • Abstract
    • The influence of the heat-input on microstructure and property in two regions of simulated welding heat-affected zone(HAZ) of 06CuNiCrMoNb steel were investigated,and the relationship between the toughness of the coarse grain heat-affected zone (CGHAZ) and microstructure were also discussed.The results show that the tensile strength of simulated HAZ dose not debase,but the low-temperature impact toughness of the CGHAZ declines rapidly on condition of heat-input above 30 kJ/cm.
