The use of commercial graphite powders (different sources and particle sizes), as electrode materials, was evaluated in an electrochemical cavity cell. The graphite powders were characterized by electron microscopy, XRD, vibrational spectroscopy, porosimetry, contact angle, Boehm titration and cyclic voltammetry. Despite similarities, the graphite powders differed significantly in terms of surface functional groups (SFGs), hydrophobicity and particle size. The surface chemistry of both graphites was ...

Maraging is a high alloy steel sensitive to the precipitation of intermetallics from a supersaturated solid solution during aging heat treatments. The precipitation phenomenon is well described in the literature, which gave rise to the alloy name regarding a martensite matrix with precipitates formed by aging treatment. Many studies have been performed to characterize this material, usually subjected to many sample preparations for transmission microscopy, which is very laborious, and few EBSD analyses. ...

The evolution of the microstructure was examined by optical and electron microscopy as well as ferritscope measurements and energy dispersive X-ray spectrometry. An electrochemical microcell was then used to characterize the electrochemical behaviour of the different weld regions. The fusion line was the most critical zone for pitting corrosion ...

Abstract Background Sleeve gastrectomy is a well-standardized surgical treatment for obesity. However, rates of weight regain after sleeve gastrectomy in long-term follow-up are relatively high. This multicenter study is the first to evaluate the use of an endoscopic sleeve gastroplasty (ESG) technique for the management of this population. Methods This was a multicenter retrospective study, including patients with weight regain following sleeve gastrectomy who underwent ESG for weight loss. Primary ...

The management of laparoscopic sleeve gastrectomy leaks remains a challenge. This can be treated with placement of self-expandable metal stents, which are most effective in the acute and early settings. However, migration is a frequent adverse event (AE). Novel, fully covered stents with a larger proximal flare to limit migration designed specifically to treat postsleeve leaks were recently introduced.The aim of this study was to evaluate the safety and efficacy of a novel stent specifically designed ...

An empirical method is developed, based on the calculated theoretical elastic-strain energy, to predict the phase formation and its stability for complex concentrated alloys. The method prediction quality is compared with the traditional empirical rules based on the atomic-size mismatch, enthalpy of mixing, and valence-electron concentration for a database of 235 alloys. The "elastic-strain energy vs. valence-electron concentration" criterion shows an improved ability to distinguish between single- ...

A design of experiments (DoE) approach was employed to systematically characterize the effects of both oxygen concentration and cooling rate on the amorphous and crystalline phase fractions in the Zr48Cu46.5Al4Nb1.5 bulk metallic glass composite (BMGC) alloy. Specifically, four distinct oxygen concentrations and five distinct cooling rates were used. Phase quantification was achieved using Rietveld refinement of synchrotron X-ray diffraction (XRD) data.

Fe–Mn–Si–Cr–Ni alloys are known by their shape memory properties, however, oxidation studies are still incipient. This study evaluated an Fe-17Mn-5Si-10Cr-4Ni-VC alloy on cyclic oxidation tests at 800, 900 and 1000 °C. Mass variation was evaluated and oxide layers were examined by SEM, EDS and XRD. An anomalous mass variation was observed: after initial spallation, the material restarted mass gain. The formed Mn-depleted zone changed the austenite microstructure to ferrite on the metal/oxide interface ...

Background and Aims The obesity epidemic has led to increased use of Roux-en-Y gastric bypass (RYGB). These patients have an increased incidence of pancreaticobiliary diseases, yet standard ERCP is not possible because of surgically altered gastroduodenal anatomy. Laparoscopy-assisted ERCP (LA-ERCP) has been proposed as an option, but supporting data are derived from single-center small case series. Therefore, we conducted a large multicenter study to evaluate the feasibility, safety, and outcomes of LA-ERCP. ...

We report a basin-hopping Monte Carlo investigation within the embedded-atom method of the structural and energetic properties of bimetallic ZrCu, ZrAl, and CuAl nanoclusters with 55 and 561 atoms. We found that unary Zr55, Zr561, Cu55, Cu561, Al55, and Al561 systems adopt the well known compact icosahedron (ICO) structure. The excess energy is negative for all systems and compositions, which indicates an energetic preference for the mixing of both chemical species. The ICO structure is preserved ...

A new and simple criterion with which to quantitatively predict the glass forming ability (GFA) of metallic alloys is proposed. It was found that the critical cooling rate for glass formation (RC) correlates well with a proper combination of two factors, the minimum topological instability (λmin) and the Δh parameter, which depends on the average work function difference (Δφ) and the average electron density difference (Δnws1/3) among the constituent elements of the alloy. A correlation coefficient (R2) ...

The main aim of this study was to compare the fatigue resistance of welded joints produced by FSSW process and riveted joints of AA2024 alloy. The specimens welded with the best preliminary parameters determined by previous tensile shear tests were tested in fatigue under load control, R=0.1, at room temperature. Two welding parameter sets were used, and P-N curves (load versus cycles) were plotted, using 2×106 cycles as the fatigue life limit. A similar curve was obtained for riveted specimens. ...

The crystallisation behaviour for alloys in the Al-rich corner in the Al–La–Ni system is reported in this paper. Alloys were selected based on the topological instability criterion (λ criterion) calculated from the alloy composition and metallic radii of the alloying elements and aluminum. Amorphous ribbons were produced by melt-spinning and the crystallisation reactions were analysed by X-ray diffraction and calorimetry. The results showed that increasing the values of λ from 0.072 to 0.16 resulted ...

The glass-forming ability (GFA) of metallic alloys is associated with a topological instability criterion combined with a new parameter based on the average electronegativity difference of an element and its surrounding neighbours. In this model, we assume that during solidification the glassy phase competes directly with the supersaturated solid solution having the lowest topological instability factor for a given composition. This criterion is combined with the average electronegativity difference ...

The best glass forming compositions for Zr–Cu and Ti–Ni systems are well predicted by this new approach. Although the new criterion needs further refinement, it is concluded that the proposed approach is a promising ...

By applying the λ criterion, a topological instability criterion proposed to predict the crystallisation behaviour of Al-based systems, we show that it is also successfully possible to reproduce compositional ranges where binary and ternary bulk metallic glasses (BMGs) have recently been obtained. Our results indicate that the good glass-former composition(s) lie( ...
