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

TL;DR: In this article, the authors used phenomenological-empirical fitting models to assess the dose (displacement-per-atom, dpa), irradiation temperature (Ti) and test temperature (Tt) dependence of yield stress changes (Δσy), as well as the corresponding dependence of sub-sized Charpy V-notch impact test transition temperature shifts (�Tc).
Journal ArticleDOI

A Physically Based Correlation of Irradiation-Induced Transition Temperature Shifts for RPV Steels

TL;DR: In this article, a physically-based, empirically calibrated model for estimating irradiation-induced transition temperature shifts in reactor pressure vessel steels, based on a broader database and more complete understanding of embrittlement mechanisms than was available for earlier models, is presented.
Journal ArticleDOI

Evolution of manganese–nickel–silicon-dominated phases in highly irradiated reactor pressure vessel steels

TL;DR: In this article, Atom probe tomography was used to study the formation of Mn-Ni-Si-dominated precipitates in irradiated Cu-free and Cu-bearing reactor pressure vessel steels.
Journal ArticleDOI

Cleavage fracture and irradiation embrittlement of fusion reactor alloys: mechanisms, multiscale models, toughness measurements and implications to structural integrity assessment

TL;DR: In this paper, the authors describe the highly efficient master curve shifts (MC-ΔT) method to measure and apply cleavage fracture toughness, KJc(T), data and show that it is applicable to 9Cr martensitic steels.
