Abstract
Uranium-rich U-Zr-Nb alloy is considered as a good alternative fuel for fast reactors from the perspective of excellent dimensional stability and desired thermo-physical properties to achieve higher burnup. Detailed investigations related to the structural and microstructural characterization, thermal expansion, phase transformation, microhardness were carried out on Uâ6Zr, Uâ4Zrâ2Nb, Uâ2Zrâ4Nb and Uâ6Nb alloys (composition in wt%) where the total amount of alloying elements was restricted to 6â¯wt%. Structural, microstructural and thermal analysis studies revealed that these alloys undergo a series of transformations from high temperature bcc γ-phase to a variety of equilibrium and intermediate phases depending upon alloy composition, cooling rate and quenching. The structural analysis was carried out by Rietveld refinement. The data of UâNb and UâZrâNb alloys have been highlighted and compared with binary UâZr alloy.
