In order to study the origin of the scatter in the fracture toughness values by small specimens in the transition region, the J-integral measurement in the fracture toughness transition region was performed using more than 100 small specimens of Ni-Cr-Mo-V steel, and fractured surfaces were studied very carefully, aiming to obtain better understanding of the scatter in the small-specimen toughness. The study discloses that a major portion of the scatter was caused by the scatter in the length of the preceding dimple crack, which was generated at the fatigue precrack before the initiation of the final cleavage fracture. A method to predict the lower bound of the scatter in the small-specimen fracture toughness was also proposed.
