National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

U.S. NHMFL 60 T Long Pulse Magnet Failure.

DE2001786731

Publication Date	2001
Personal Author	Sims, J. R.; Schillig, J. B.
Page Count	5
Abstract	The 60 T long pulse magnet operated by the U.S. National High Magnetic Field Laboratory at Los Alamos National Laboratory, Los Alamos, New Mexico failed catastrophically on July 28, 2000. The failure was investigated and the cause was determined to be unusually low toughness in the nitrogen strengthened manganese stainless steel (Nitronic-40(tm)) reinforcing material. The source of the reduced toughness condition was a sigma phase conversion int he microstructure. The magnet failure, failure investigation and results of the investigation are described. Plans for the construction of the successor magnet, the 60 tesla long pulse Mark II, are described.
