Performance test of bend fatigue testing machine for small specimens

Endo, Shinya; Kikuchi, Kenji; Saito, Shigeru; Hamaguchi, Dai; Yong, D.*

Post Irradiation Examination (PIE) of materials irradiated at SINQ, with 580 MeV proton beam, of PSI in Switzerland, has been performed under an international cooperation, which covers tensile, bending fatigue and TEM observation. There are a number of irradiated materials stored at hot laboratory and PIE has not conducted yet at PSI. We set up testing machine, developed at JAEA, to the hot laboratory of PSI in order to obtain materials design data base useful for a construction of nuclear transmutation facility. Testing machine performance was investigated by using un-irradiated specimens. Optical and SEM observation of fractured specimen was done and failure mechanism was investigated. PIE is to be done at PSI.
