Compilation of low-cycle fatigue data of reactor structural materials

This report summarizes the low-cycle fatigue data of reactor structural materials, which had been acquired by a series of contract researches between JAERI and Japan Welding Engineering Society (JWES) concerning the fatigue life evaluation of reactor structural components and the material aging from FY1979 to FY1990. These contract researches had been executed by subcommittees organized under cooperation with universities, neutral institutions and the industry. Subsequently, the fatigue data base 'FADAL' was developed by accumulating fatigue data acquired by the above contract researches as well as those obtained from literature survey under contract between JAERI and High Pressure Institute of Japan (HPI). Low-cycle fatigue data compiled in this report are tabulated and illustrated as εta-Nf diagram by retrieving the FADAL. (author)
