Description

Oxide dispersion strengthened (ODS) martensitic steel is a candidate material for fuel cladding of sodium cooled fast breeder reactor (SFR). ODS steel shows high strength at high temperature because of the dispersion of oxide particle in matrix and high thermal conductivity. The operating temperature of SFR was 550.deg.C and precipitates, such as M23C6, MX, Laves phase, were observed after long exposure at the operating temperature of SFR for martensitic Cr-Mo steel. To design SFR, the effect of aging on mechanical properties should be evaluated as a function of temperature because these precipitates affect mechanical properties. In this study, tensile properties of martensitic ODS steel were investigated after aging at high temperature. ODS steel shows high strength but exhibits low elongation at temperature range from RT to 500.deg.C. Tensile properties are little changed by aging. Dynamic strain aging is not observed at temperature range from RT to 700.deg.C for unaged and aged steels
