| Popis: | Creep behaviour of Ti modified 14Cr–15Ni austenitic stainless steel (designated as D9I SS), being considered for the cladding material in Prototype Fast Breeder Reactor (PFBR), is analysed using theta (θ) projection method and with a new relation. The material D9I SS, apart from fuel cladding tubes, is also being considered as a clad wrapper tube (long hexagonal tube) of FBRs that houses the fuel clad tubes. The new methodology is found to predict the creep behaviour much better than traditional 4-θ and 6-θ approaches. Further, the minimum creep rate, time to reach various strain levels and rupture life of the alloy D9I SS (with varying Titanium contents) have also been successfully predicted using this new relation. |
