Superconductor Materials. A Comparison of Selected Strategic Materials Technologies in the U.S. and U.S.S.R.
Abstract
The use of superconductive materials in rotating electrical machinery would permit a considerable reduction in equipment size, which would be especially useful for naval applications. All of the known materials for such applications, however, must be maintained at temperatures below 20K (-253C) in order to keep them in the superconductive state. Materials of construction for equipment used to maintain cryogenic temperatures must be sufficiently ductile at those temperatures to avoid brittle failures in service. Research and development on superconductive machinery, including choice of materials of construction (or development of such materials) is underway in the United States, primarily under sponsorship by ARPA. The objective of the work described in this report was to determine the status of similar work in the USSR. A survey of Soviet research aimed at discovering materials that are superconductive at temperatures above 20K was included. The method of approach was to survey systematically the recent Soviet literature.
