摘要：
In this paper, experimental results involving the effect of stress and temperature on creep behaviour of induction pressure welded (IPW) 2.25Cr-1Mo steel are presented. Creep rupture tests were conducted at 550-700 degrees C in steps of 50 degrees C over a stress range of 112.5-180 MPa. Above 650 degrees C failure of the specimen was enhanced due to the microstructural instability. Failure in the specimens occurred invariably in the heat affected zones (HAZ), and the fracture surfaces indicated ductile failure.
