Dynamic transformation from alpha (HCP) to beta (BCC) phase in a zirconium alloy was
revealed by the use of in-situ neutron diffraction during hot compression. The dynamic …

A critical review is presented of all published data on phase transformation in zirconium and
its alloys. Topics discussed include: The α→ β transformation; factors affecting the stability of …

Previous papers pointed out the influence of long-term service exposures on the thermal-
mechanical behavior of Zr alloys in LOCA conditions and, especially, the impact of in-service …

Microstructures of low-tin Zircaloy-2 specimens subjected to quenching from β to α phase
have been studied using optical and scanning electron microscopy (SEM). The specimens …

The transformation characteristics of rapidly heated (≈ 100–200° C/s) and β-quenched
zircaloy-4-O alloys (0.1–1 wt% O) have been investigated in detail. Analyses of the heating …

The transmission of thermal neutrons through an object is affected by the microstructure and
crystallographic texture of the composing material. As a result, the total neutron cross section …

In this paper, we report the effect of a 20% predeformation on the microstructural evolution of
a Zr–0.85 Sn–0.4 Nb–0.4 Fe–0.1 Cr–0.05 Cu alloy during aging between 550 and 700° C …

This work indicates that the matrix content of the alloying elements iron, chromium, and
nickel in as-produced commercial Zircaloy-2-type materials is lower than what has been …

Zirconium alloys are used in the nuclear industry as fuel rod cladding. They are chosen for
this role because of their good mechanical properties and low thermal neutron absorption …

Fiber laser welding of R60702 pure Zr was performed in this study. The joint was composed
of base metal (BM), fine grain heat affected zone (FGHAZ), coarsened grain heat affected …
