The dynamic fracture toughness for a carburized steel, SCM 415, was evaluated using a computer-aided instrumented Charpy impact testing method (CAI-system) and the impact response curve method in the standard Charpy-size carburized and hardened specimen with a machine notch. The fatigue crack was set in the notch tip. The 0.2 mm precracked specimens showed a transition behavior in the relation between the dynamic fracture toughness and the temperature, whereas the 0.4 mm precracked ones did not show this phenomenon. Therefore, the hardness and carbon content in the position of the precrack tip inside the hardened case gave an important effect to the dynamic fracture toughness of the material such as carburized steel.
