摘要: RRR300超导铌板是制作超导腔的主要材料,为了减小制备超导腔时的阻力,有必要进行退火,提高材料塑性。通过采用不同退火温度对RRR300超导铌板进行退火,观察RRR300超导铌板显微组织、力学性能以及RRR值变化,确定了600℃为RRR300超导铌板的结晶转变温度,750℃为最理想的热处理温度,此温度下,力学性能、显微组织及RRR值达到一个理想状态。

Abstract: The RRR300 superconducting niobium plate is the main material for making superconducting cavities. In order to reduce the resistance when making superconducting cavities, it is necessary to anneal the superconducting niobium plate to improve its plasticity. In the study, RRR300 superconducting niobium plate is annealed at different annealing temperatures, and the changes of microstructure, mechanical properties and RRR of RRR300 superconducting niobium plate annealed are observed.Resultsshow that 600 ℃ is the crystallization transition temperature of RRR300 superconducting niobium plate, and that 750 ℃is the ideal treatment temperature, at which temperature, microstructure, mechanical properties and RRR can reach an ideal state.
