YBCO厚膜用立方织构Ni基带的X射线衍射研究

X-ray Study of Cube Textured Ni Substrate for YBCO Thick Films

摘要:

用冷轧和再结晶退火技术制备了ＹＢＣＯ超导厚膜用的立方织构Ｎｉ基带。并且对所制备的立方织构Ｎｉ基带进行了Ｘ射线衍射研究。提出并讨论了Ｎｉ基带立方织构质量评价实验中容量出现的问题。

Abstract:

High quality, sharp cube textured Ni substrates for YBCO thick films have been fabricated by a cold rolling and recrystallization annealing process. The prevalent quality evaluation of the cube textured Ni substrate are studied.. The results show that (001) spectrograms obtained from scanning and FWHM of (001) rocking curves by 6 scanning are relative to the f angles.Correspondent: Liu Chunfang, Professor, Superconducting Material Research Center, Northwest institute for Nonferrous Metal Research, Xi'an 710016, P.
