Effect of neutron irradiation at low temperature on the embrittlement of the reduced-activation ferritic steels

On the effects of irradiation and helium on the yield stress changes and hardening and non-hardening embrittlement of ∼8Cr tempered martensitic steels: Compilation and analysis of existing data

“…6(a)-(c) [4,7,20,22,26,27,[50][51][52][53][54][55][56][57][58][82][83][84][85][86][87][88][89][90][91][92][93][94][95][96]. Note, these plots do not include a comprehensive database assembled by Schneider and co-workers [93,94] on a variety of %9Cr-W and %9Cr-Mo steels, including some alloys with Ni additions, as well as F82H.…”

“…However, in this case, the alloy classes were analyzed separately, since there were more significant differences between the various steels and a common T i binning was not as useful. The data [4,7,20,22,26,27,[50][51][52][53][54][55][56][57][58][82][83][84][85][86][87][88][89][90][91][92][93][94][95][96], which in most cases were very scattered, could be reasonably fit using a simpler nonsaturating function • The ΔT c /Δσ y irradiations at T i < 400°C are generally less than the corresponding fracture toughness indexed ΔT o /Δσ y shifts. Thus the ΔT c from sub-sized Charpy tests are probably non-conservative, and may seriously underestimate the embrittlement potential of TMS.…”
