A method for joining segments of 123 superconductor to form a superconducting article.

摘要

A method of fabricating articles from segments of anisotropically conducting 123 superconductor such that the current transport properties of the article are comparable to those of the individual segments. The segments to be joined are examined to determine the orientation of the ab plane. Contact surfaces are formed where necessary and the segments are brought into contact and the ab planes are brought into parallel alignment. The contacted segments are elevated in temperature and static pressure is applied to accelerate reaction across the interface of the contact surfaces. The so-formed coherent article is then cooled at a controlled rate. <IMAGE>
