Abstract: Zr-1Nb alloy is normally processed in two phase region to get desirable microstructure and properties for fuel cladding tube application in the nuclear reactor. Thus, it is important to know the deformation behavior of individual phases in the two phase region. However, the conventional approach to develop processing maps is to use flow stress data obtained from hot compression experiments, without accounting for the phases present at different temperatures. This approach fails to bring out the details about the operating deformation mechanism in the individual phases. In order to bring out these details, two new approaches are proposed for developing processing maps. The validity of the approaches is confirmed by performing microstructural analysis using electron backscattered diffraction (EBSD) studies. EBSD analysis of the microstructures obtained after deformation in the two phase region confirmed that α−phase had undergone dynamic recrystallization (DRX) whereas, β−phase exhibited coarse elongated grains. Processing maps developed using the new approaches were able to predict domains of high dissipation efficiency, which is corroborated by microstructural analysis. Also, one of the novel approaches proposed in this work could delineate the contribution of each phase in the two phase region. © 2017 Elsevier B.V.
