Zirconium hydride precipitation kinetics in Zircaloy-4 observed with synchrotron X-ray diffraction
Matthew S. Blackmur,Joseph D. Robson,Michael Preuss,O. Zanellato,Robert J. Cernik,San-Qiang Shi,Fabienne Ribeiro,Jérôme Andrieux +7 more
TL;DR: In this article, high-energy synchrotron X-ray diffraction was used to investigate the isothermal precipitation of δ-hydride platelets in Zircaloy-4 at a range of temperatures relevant to reactor conditions, during both normal operation and thermal transients.
Journal ArticleDOI
Precipitation in the Fe-Mo and Fe-Au systems
TL;DR: In this paper, a general hypothesis of atom size effects for G.P. zone formation is discussed and results are presented of precipitation in the systems Fe-Au and Fe-Mo. Techniques used are resistivity measurements and electron microscopy.
Journal ArticleDOI
Comments on the Nucleation Theorem
TL;DR: In this paper, a critical analysis of the nucleation theorem in its different formulations is presented, and the conditions of validity of this particular formulation are discussed both for the original version (developed for one-component systems) and the generalization to multicomponent systems considered here.

Effects of Deformation (Strain) and Heat Treatment on Grain Boundary Sensitization and Precipitation in Austenitic Stainless Steels
TL;DR: In this paper, a TEM examination of precipitation occurring in type 316 stainless steel pipe grain boundaries has shown they exhibit many microstructural features that seem to be coincident with grain boundary microstructures, particularly ledges.

Transport-controlled hydrothermal replacement of calcite by Mg-carbonates
TL;DR: In this article, the reaction of single calcite crystals with a Mg-rich fluid at 200 °C leads to the formation of a zoned reaction rim consisting of magnesite and, for intermediate times, Ca-rich dolomite.
