| 英文摘要 | Zr-based alloys have been used as cladding tubes in nuclear reactors for several decades due to their superior mechanical properties, good corrosion resistance and low neutron absorption cross-section. Zr alloys consist of hcp-structured alpha-Zr matrix and dispersed precipitate particles. These precipitate particles play a key role in improving the service performance of the alloy. In general, the manufacturing of Zr-based alloy tubes or sheets involves a series of deformation and annealing processes, which lead to a modification of the precipitate particles in size and distribution and an improvement of comprehensive properties of the alloys. In this work, the effect of intermediate heat treatment processes on precipitate particles and air oxidation characteristics of Zr-1Nb-0.2Y (mass fraction, %) alloy was studied. With increase of rolling and annealing times, the oxidation resistance of Zr-1Nb-0.2Y alloy was improved. The final product from manufacturing route II with intermediate annealing process of 640 degrees C, 3 h+570 degrees C, 3 h was proved to be most resistant to oxidation in 420 degrees C air. TEM images and EDS results showed that relevant parameters such as precipitate particle volume fraction, precipitate particle mean diameter, Nb+Y content (including mean content and total content) in precipitate particles were modified by intermediate annealing processes, which essentially influenced the oxidation characteristics of Zr-1Nb-0.2Y alloy. The smaller the mean size of precipitate particle and the higher the Nb+Y content in the precipitate particle are, the better the resistance to air oxidation of Zr-1Nb-0.2Y alloy. |
