Fracture behaviour of ferritic/martensitic steels in DBT region characterized using CT and TPB specimen geometries

  • Abhishek Tiwari
  • R. N. Singh
Brief Note


Fracture behaviour of two different ferritic martensitic grades of steel, namely Indian Reduced Activation Ferritic Martensitic steel and modified 9Cr-1Mo steel (Mod 9Cr-1Mo,P91), are investigated in DBT region using master curve approach. The effects of single and multi temperature methods of master curve and strict censoring, on reference transition temperature are studied. The effect of specimen geometries is studied by comparing CT and TPB geometries. Also the differences in reference transition temperature arising due to the difference in two grades of ferritic martensitic steels are studied.
