摘要：
The creep crack growth behaviour of type 316 stainless steel and its weldment in the temperature range 600$DGC to 800°C has been studied under plane stress conditions. The creep crack growth (CCG) rate bears a relation with the load point deflection (LPD) rate independent of the load. The parameters stress intensity factor, K, and the energy rate line integral C*, have been correlated with the CCG rate. At 600°C the crack growth takes place along the interface between austenite and the delta ferrite. At 700° and 800°C sigma phase formation is dominant and crack growth is along the sigma phase and austenite.
