Microstructural examination of V-(3-6%)Cr-(3-5%)Ti irradiated in the ATR-A1 experiment

Microstructural examination results are reported for four heats of V-(3-6%) Cr-(3-5%)Ti irradiated in the ATR-Al experiment to similar to4 dpa at 200 d egreesC and 300 degreesC to provide an understanding of the microstructural evolution that may be associated with degradation of mechanical properties . Fine precipitates were observed in high density intermixed with small def ect clusters for all conditions examined following the irradiation. The irr adiation-induced precipitation does not appear to be affected by preirradia tion heat treatment or composition. (C) 2000 Elsevier Science B.V. All righ ts reserved.
