Directional Solidification in YBCO Superconductors

摘要:

讨论了YBCO高温超导体定向凝固中所涉及的包晶反应、界面稳定性及其形态控制、凝固取向和晶向控制等问题。并提出了定向凝固中应该注意的问题。

Abstract:

Some basic problems in preparing YBCO superconductor by directional solidification, including the peritectic reaction , the interface stability and its control , the orientation of solidification, and crystal orientation control , were discussed. Many problems have been revealed and must be overcome in the future, in order to get an optimum structure.
