The anodic dissolution behaviours of Cu, Zr and Cu–Zr alloy were analysed in LiCl–KCl at 500°C by anode polarization curve and potentiostatic polarization curve. The results show that the initial and fast-dissolving potentials of Cu are −0.50 and −0.29 V, and Zr are −1.0 and −0.88 V, respectively. But, in the Cu–Zr alloy, the initial and fast-dissolving potentials of Cu are −0.52 and −0.41 V, and Zr are −0.96 and −0.92 V, respectively. The potentials satisfy the selection dissolution principle that Zr in the alloy dissolves first, while Cu is left in the anode and is not oxidized. The passivat

An experimental investigation on the solubility of Zr in Cu-Sn alloy was conducted in a resistance furnace. The solubility of Zr in Cu-Sn alloy was determined by investigating the influence of different conditions such as the ratio of Cu-Sn alloy and temperature. The solubility of Zr in Cu-Sn alloy changes with the proportion of Cu and Sn, and it increases with the increasing of Cu content. The experimental temperature has a significant effect on the solubility of Zr in Cu-Sn alloy. The maximum solubility of Zr in Cu-Sn alloy is 6.2 mass % at 900 °C with the mass ratio of Cu : Sn = 8:2.

Zr-Cu amorphous films were prepared by radio-frequency (RF) magnetron sputtering on glass substrate using two kinds of the elemental composite targets: Cu chips on Zr plate and Zr chips on Cu plate. It was easy to precisely control chemical compositions of sputtered films by selecting the chip metal and the number of chips. It is possible to accurately estimate the film compositions by using the sputtered area and the deposition rate of Cu and Zr. XRD analysis on every as-sputtered film showed the broadened pattern.

A modified embedded-atom method (MEAM) interatomic potential for the Cu–Zr system has been developed based on the previously developed MEAM potentials for pure Cu and Zr. The potential describes fundamental physical properties and alloy behavior of the Cu–Zr binary system reasonably well. The applicability of the potential to atomistic investigations of mechanical and deformation behavior for the Cu–Zr binary and Cu–Zr-based multicomponent amorphous alloys is also demonstrated by showing that fully relaxed and realistic amorphous structures can be generated by molecular dynamics simulations.

With the effects of electronic structure and atomic size being introduced, a revised model to calculate the viscosity of the bulk metallic glass alloys was proposed and the viscosity of ternary Zr-Al-Cu, Zr-Ni-Al and quaternary Zr-Al-Ni-Cu systems are calculated in this paper, and the computed results agree well with the empirical one. The sequence of viscosity of different systems is: VZr-Al-Cu <VZr-Al-Ni<.VZr-Al-Ni-Cu. To Zr-Al-Cu and Zr-Ni-Al, the highest viscosity locates in the composition range of XZr=0.37-0.86, XCu=0-0.40 and XZr = 0.45-0.79, XAl = 0.12-0.50, respectively. And to

Effect of electrochemical absorption of hydrogen has been studied on the Zr-based amorphous alloys. The influence of hydrogen absorption on the stability of the amorphous phase and its crystallisation was investigated. Additionally, the cathodic hydrogen reaction mechanism on the surface of the alloy, the reversibility of the absorbed hydrogen and the hydrogen diffusion in the alloy were studied. These alloys are able to absorb large amounts of hydrogen (>1:1 hydrogen to metal ratio) but a rearrangement of the amorphous matrix takes place so that Cu rich areas are detected on the surfac

(Bulk) metallic glasses ((B)MGs) are known to exhibit the highest yield strength of any metallic material (up to 5GPa), and show an elastic strain at ambient conditions, which is about ten times larger than that of crystalline materials. Despite these intriguing mechanical properties, BMGs are not used as structural materials in service, so far. The major obstacle is their inherent brittleness, which results from severe strain localization in so-called shear bands. MGs fail due to formation and propagation of shear bands. A very effective way to attenuate the brittle behaviour is to incorporat

While inelastic mechanical behaviour of crystalline materials is well-understood in terms of lattice defects, bulk metallic glasses (BMGs) pose significant challenges in this respect due to their disordered structure. They can be produced by rapid cooling from the liquid state (among other technique) and, thus can be frozen as vitreous solids. Due to the absence of a long-range order in atomic structure and a lack of defects such as dislocations, BMGs generally show unique mechanical properties such as high strength and elastic limit, as well as good fracture toughness and corrosion resistance

In the course of this PhD thesis metastable Cu50Zr50-xTix (0≤ x ≤ 10) and (Cu0.5Zr0.5)100-xAlx (5 ≤ x ≤ 8) alloys were prepared and characterised in terms of phase formation, thermal behaviour, crystallisation kinetics and most importantly in terms of mechanical properties. The addition of Al clearly enhances the glass-forming ability although it does not affect the phase formation. This means that the Cu-Zr-Al system follows the characteristics of the binary Cu-Zr phase diagram, at least for Al additions up to 8 at.%. Conversely, the presence of at least 6 at.% Ti changes the crystallisation

Abstract The effect of temperature on stress corrosion crack growth rates was studied using four commercial alloys: An Al-Mg-Zn alloy (7000-Series), an Al-Cu alloy (2000-Series), a Mg-rare earth alloy and a Zr 2.5% Nb alloy. Stress Corrosion crack growth rate data were obtained using fracture mechanic specimens which were tested in high purity water in the temperature range of -10°C to 320°C, depending on the alloy. Attention was directed towards region II behaviour, where the crack propagation rate is independent of stress intensity but sensitive to test temperature. The experimental activati

Abstract The corrosion behavior of two Al- Li-Cu-Zr-Ge alloys, with and without Mg, was studied. The types of corrosion tests conducted included exfoliation corrosion, crevice corrosion, constant immersion studies and anodic polarizations. The alloys were tested in both the underaged and overaged tempers. The heat treatments resulted in significant microstructural differences due to the precipitation of numerous metastable and equilibrium phases. The addition of magnesium results in a more consistent corrosion behavior with aging time, as well as a lower susceptibility to general corrosion, a

Abstract Stress corrosion cracking (SCC) susceptibility of Al-Zn-Mg-Cu-Zr base 7010 alloy of two different tempers viz. T6 (peak aged - two step aging) and T73 (over aged - three step aging) have been investigated in air and an aqueous environment (non-deaerated 3.5 wt.% NaCl solution) by slow strain rate testing (SSRT) as well as U-bend testing. The tests have been carried out at 10-5/s and 10-6/s strain rates. In over aged temper (T73), the alloy exhibits substantial improvement in SCC resistance with minimal reduction in the ultimate tensile strength as compared to the peak aged temper (T6)

Camilo Ponce Enriquez is in the southwest coastal zone of Ecuador, and it is surrounded by 4 river basins (Gala, Tenguel, Siete and Pagua) with an area of 1,780 km2. Mining has been the main economic activity since 1980 and is classified as Artisanal and Small-Scale Mining Activity. However, since 2000s there is evidence of contamination by heavy metals in water and sediments due to irregular mining practices and inefficiency environmental�s regulations. Despite the evidence, there are not enough scientific studies, and few reports are published about chemistry and contamination. The study goa
