On the Stability and Structure of Zr-Cu and Zr-Ti-Cu Alloys

Solid State Phenomena, 1998
The alloys Zr-Cu-Ti and Zr-Cu have been prepared by melt-spinning and mechanical alloying techniques. Their thermal behaviour and structure factors have been investigated. Thermal properties obtained by differential scanning calorimetry, of an amorphous alloy (54Zr34Cu10Ti), were tested in argon and nitrogen atmospheres.

Diffusion and chemical activity of Zr-Sn and Zr-Ti systems

Physical Review B, 1986
A modified evaporation method was used to determine the diffusion coefficients and the emission rates of Sn and Ti in Zr-Sn and Zr-Ti, respectively, at temperatures between 1605 and 1970 K. Results show that both Sn and Ti diffuse in their respective alloys via a vacancy mechanism.

Contribution to the Zr-rich part of the Zn-Zr phase diagram

Journal of Phase Equilibria and Diffusion, 2004
The reaction of zinc vapor with Zircaloy-4 and nuclear grade zirconium was investigated with various analytical techniques: optical metallography, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Based on the results, the Zr-rich part of the Zn-Zr phase diagram was revised. A eutectoid decomposition of (βZr) occurs at 718±

Semi-automated production of ⁸⁹Zr-oxalate/⁸⁹Zr-chloride and the potential of ⁸⁹Zr-chloride in radiopharmaceutical compounding.

Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine, 2016
Interest in using (89)Zr is rapidly increasing for immuno-PET applications due to its unique characteristics and increased availability. The focus of this study was to develop an optimized semi-automated methodology for producing (89)Zr-oxalate/(89)Zr-chloride, and evaluate the potential application of (89)Zr-chloride for radiopharmaceutical ...

Fundamental Study on the Corrosion Mechanism of Zr-0.2Fe, Zr-0.2Cr, and Zr-0.1Fe-0.1Cr Alloys

2000
Corrosion and hydrogen pickup properties were investigated on sheet materials of pure Zr, Zr-0.2 wt%Fe, Zr-0.2 wt%Cr, and Zr-0.1 wt%Fe-0.1 wt%Cr which were given an intermediate anneal of 853 K or 1003 K, and a final anneal at 853 K. To clarify the substantial effects of iron and chromium, impurities were minimized by using crystal bar zirconium and ...
