Journal ArticleDOI
Recent progress of R&D activities on reduced activation ferritic/martensitic steels
Qunying Huang,Nadine Baluc,Y. Dai,S. Jitsukawa,Akihiko Kimura,J. Konys,Richard J. Kurtz,Rainer Lindau,Takeo Muroga,G.R. Odette,Baldev Raj,Roger E. Stoller,Lizhen Tan,Hiroyasu Tanigawa,A.-A.F. Tavassoli,Takuya Yamamoto,Farong Wan,Yican Wu +17 more
TL;DR: In this article, the authors present recent RAFM steel results obtained in ITER partner countries in relation to different TBM and DEMO options, and evaluate the mechanical properties of these steels before and after irradiation and in contact with different cooling media.
Journal ArticleDOI
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
Peter B. Wells,Takuya Yamamoto,Brandon D. Miller,Tim Milot,James I. Cole,Yuan Wu,G. Robert Odette +6 more
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.
