Effect of Creep Holding Time on the Fatigue Behavior in P92 Steel Weldment at High Temperature
In this study, the crack growth behavior in P92 steel (9%Cr-2%W) weldment was investigated at 600ı under the load of trapezoidal wave shape with various holding times. The relationship between the crack growth behavior and holding time was studied and it was characterized using the ΔK and (Ct)avg parameters. The number of micro-voids/cavities at the crack tip and fracture modes were examined and the relationship between crack growth rate and holding time was investigated.
