The vanadium-zirconium alloy system
<p>This investigation of the vanadium-zirconium alloy system produced evidence on several points concerning the equilibrium diagram. It was shown that a eutectic reaction between an intermediate phase and a zirconium-rich solid solution occurs at a temperature of 1230° +/- 10°C, and that the …

Predicting the Influence of Hydrogen on Zirconium
… corrosion process that ensues when the alloys of zirconium used as structural components and fuel claddings in nuclear reactors react with the heavy water used as coolant in the CANDU® reactors results in the production of hydrogen or deuterium. Some of this hydrogen enters the alloy and causes a …

Zirconium nitride contacts for cadmium telluride solar cells
CdTe/CdS solar cells were produced with ZrN as a back contact by magnetron sputtering. ZrN films have been produced with crystalline quality and uniformity on CdTe. With good crystalline quality and uniformity on substrate materials, ZrN films have a low resistivity of 12.3 to 22.0 μΩ-cm, …

Electrochemical study of corrosion phenomena in zirconium alloys
Shadow corrosion of zirconium alloy fuel cladding in BWR environments, the phenomenon in which accelerated corrosion is experienced when the cladding surface is in close proximity to other metals, has become a potentially life-limiting issue for BWR fuel. Recent results from experimentation at MIT, …

Predicting the equilibria of point defects in zirconium oxide : a route to understand the corrosion and hydrogen pickup of zirconium alloys
The performance of zirconium alloys in nuclear reactors is compromised by corrosion and hydrogen pickup. The thermodynamics and kinetics of these two processes are governed by the behavior of point defects in the ZrO₂ layer that grows natively on these alloys. In this thesis, we developed a …
