Embrittlement of cast stainless steels in LWR systems

  • 1. Argonne National Lab., IL (USA). Materials and Components Technology Div.

Description

Mechanical property data from Charpy-impact and J-R curve tests are presented for several experimental and commercial heats, as well as for reactor-aged material of CF-3, CF-8, and CF-8M grades of cast stainless steel. The efrects of material variables on the embrittlement of cast stainless steels are evaluated. Chemical composition and ferrite morphology have a strong effect on the extent and kinetics of embrittlement. The data are analyzed to establish the mechanisms of embrittlement. Procedures and correlations for predicting the impact strength and fracture toughness of cast components during reactor service are described. The lower-bound values of impact strength and fracture toughness for low-temperature aged cast stainless steel are defined. (orig.)
