Journal ArticleDOI
A review of microstructure evolution in zirconium alloys during irradiation
TL;DR: In this article, anisotropic interstitial diffusion has been observed in ZrSn and ZrNb alloys at temperatures between about 573 and 873 K, at least for fluences up to 7 × 10 25 n m −2.
Journal ArticleDOI
Phase instability, decomposition and redistribution of intermetallic precipitates in Zircaloy-2 and -4 during neutron irradiation
TL;DR: In this article, the structural, chemical and morphological changes of intermetallic particles of Zr(Cr, Fe)2 and Zr2(Ni, Fe), Fe 2 in Zircaloy-2 and -4 were studied.
Journal ArticleDOI
The formation of c-component defects in zirconium alloys during neutron irradiation
Malcolm Griffiths,R.W. Gilbert +1 more
TL;DR: There is a correlation between the existence of c- component defects and accelerated irradiation growth of annealed Zr and Zircaloy-2 and -4 analysis shows that these defects are vacancy, basal plane dislocation loops having Burgers vectors of b = 1 6 〈2023〉 as mentioned in this paper.
Journal ArticleDOI
Evolution of microstructure in hcp metals during irradiation
TL;DR: For pure hexagonal-close-packed (hcp) metals, the principal habit plane for dislocation loop nucleation is generally the most close-packed plane and this varies with c/a ratio as discussed by the authors.
Journal ArticleDOI
Intergranular fracture in irradiated Inconel X-750 containing very high concentrations of helium and hydrogen
C.D. Judge,Nicolas Gauquelin,Lori Walters,Michael Wright,James I. Cole,James W. Madden,Gianluigi A. Botton,Malcolm Griffiths +7 more
TL;DR: In this article, it has been observed that Inconel X-750 spacers in CANDU reactors exhibits lower ductility with reduced load carrying capacity following irradiation in a reactor environment.
