TL;DR: The powder metallurgy (P/M) process and the In Situ process are alternative technologies for producing fine fiber, multifilamentary, A15 superconductors with high overall critical current densities, Jc, at high fields and with good strain tolerance as mentioned in this paper.
Abstract: The powder metallurgy (P/M) process and the In Situ process are alternative technologies for producing fine fiber, multifilamentary, A15 superconductors with high overall critical current densities, Jc, at high fields and with good strain tolerance. Several papers were presented at the 1983 Applied Superconductivity Conference by our group.These papers, references cited therein, and related papers should be consulted for progress to that date. Because of space limitations, in this paper we will refer to these papers briefly, examine some fundamental limits to further improved performance, report on new developments in processing, outline recent results, and give some overall assessments of future directions. At this time it is clear that the performance of Nb3Sn can be improved within rather well defined limits, whereas the Jc of Nb3Al, which now surpasses Nb3Sn at high fields, is expected to show further substantial increases in performance. The discussion here is directed toward highest field applications.
