The Zr–2.5Nb alloy is used as pressure tubes in Canadian Deuterium Uranium (CANDU) nuclear reactors, and the typical starting microstructure consists of ?-Zr grains elongated both transverse longitudinal directions thin layers partially decomposed ?-Zr lying between grains. In this study, we have state-of-the-art microscopy techniques to characterise long-term thermally ? phase alloy, oxide sca...

The aim of this work is to elucidate the formation of the amorphous phase in the Cu-Zr binary alloy system. It was found that 1 mm diameter rods with a fully amorphous structure can be prepared in a relatively wide range of compositions. In contrast, the formation of 2 mm diameter rods was achieved only for the Cu64Zr36 alloy and in the range of Cu53Zr47 Cu50Zr50, which are compositions near th...

In the present work, the oxide layers developed at elevated temperature on three vanadium-free titanium alloys, of interest as implant biomaterials, were studied by Rutherford backscattering spectroscopy, elastic recoil detection analysis, and scanning electron microscopy. The chemical composition of the alloys investigated, in wt%, was Ti–7Nb–6Al, Ti–13Nb–13Zr, and Ti–15Zr–4Nb. Upon oxidation ...

Solution strengthening is a well-known approach to tailoring the mechanical properties of structural alloys. Ultimately, the properties of the dislocation/solute interaction are rooted in the electronic structure of the alloy. Accordingly, we compute the electronic structure associated with, and the energy barriers to dislocation cross-slip. The energy barriers so obtained can be used in the de...

The crystal nucleation from liquid in most cases is too rare to be accessed within the limited time scales of the conventional molecular dynamics (MD) simulation. Here, we developed a "persistent embryo" method to facilitate crystal nucleation in MD simulations by preventing small crystal embryos from melting using external spring forces. We applied this method to the pure Ni case for a moderat...

Abstract Synthesis and sputtering of the Zr-2.5Nb alloys were performed for dental implant material candidate. The alloy was synthesized by casting process in an arc melting furnace with argon atmosphere composition Zr-2.5 Nb (wt %). Surface treatment carried out Ti-N current 20 Ampere 45 minutes. Characterization microstructure SEM-EDX test followed phase identification using XRD analysis. har...
