Creep Behaviour and Microstructure Evolution in Super 304H-P92 Heterogeneous Welds
Original language description
The paper deals with results of long-term stress rupture tests on "cross-weld" specimens made of Super 304H-P92 heterogeneous welds. Stress rupture tests were carried out at temperatures of 625 and 650 oC up to 20,000 hours to rupture. Creep rupture strength and WSF values of Super 304H-P92 welds for 10,000 hours at both 625 and 650 oC were calculated. The preferential location of failure was the intercritical part of the heat affected zone in P92 steel. Hardness of both base materials did not show significant changes during creep exposure at both 625 and 650 oC. However, gradual hardening of the weld metal occurred. Metallographic studies were performed in individual parts of heterogeneous welds. A special attention was paid to precipitation reactions in both base materials and heat affected zones. A residual content of vanadium in Super 304H steel affected precipitation processes. Vanadium partly substituted niobium in the modified Z-phase ((V,Nb)CrN).
