This report contains results of a research program to produce material property data that will facilitate design and development of cryogenic structures for the superconducting magnets of magnetic fusion energy power plants and prototypes. The program was conceived and developed jointly by the staffs of the National Bureau of Standards and the Office of Fusion Energy of the Department of Energy it is managed by NBS and sponsored by DoE. Research is conducted at NBS and at various other laboratories through subcontracts with NBS. The reports presented here summarize the sixth year of work on the low temperature materials research program. Highlights of the results are presented first. Research results are given for the four main program areas structural alloys, weldments and castings, nonmetallics, and technology transfer. Objectives, approaches, and achievements are summarized in an introduction to each program area. The major portion of the program has been the evaluation of the low temperature mechanical and physical properties of stainless steel base metals, welds, and castings, with particular emphasis on the nitrogen strengthened stainless steels. Developmental steels with manganese additions are also under investigation. Codes and standards development received increased emphasis this year, especially as related to low temperature property measurements. Work has been done on the standardization of industrial laminates for low temperature applications and on the measurement of nonmetallic composite properties at cryogenic temperatures. Modeling of the elastic and fracture behavior of woven fiber reinforced composites has been initiated this year.
