摘要：
The influences of temperature and loading rate on fracture toughness of two pipe-line steels at initiation, K(ld), and at arrest, K(la), and on stretch zone height were measured using specific techniques. Particular attention was given to the mechanism of delamination, typical for the gas internal pressure pipe fracture.
