摘要
研究了校平工艺对RRR300超导铌板横纵向力学性能的影响,结果表明:随着校平辊缝的减小,校平次数增加,屈服强度明显增加,硬度增加;材料整体主体组织无明显变化,但表层有晶粒状态改变的趋势。
The effects of leveling process on the transverse and longitudinal mechanical properties of RRR 300 superconducting niobium plate were studied. Results showed that with the decreasing of kun seam, the leveling times increased, so did the yield strength and hardness. After leveling, the overall metallographic structure of the plate had no obvious change, but the grain state of the surface layer had a tendency to change.
