Microstructural examination in FFTF irradiated manganese stabilized martensitic steel.

摘要

Transmission electron microscopy has been performed on FFTF irradiated specimens of manganese stabilized martensitic steels in order to identify the cause of irradiation-induced embrittlement. Examinations demonstrated the presence of Fe--Cr--Mn chi phase, a body-centered cubic intermetallic phase, known to be detrimental to mechanical properties. 6 refs., 3 figs., 2 tabs.
