Iron-nickel (Fe-Ni) alloy nanoribbons were reported for the first time by deoxidizing NiFe2O4 nanoribbons, which were synthesized through a handy route of electrospinning followed by air-annealing at 450 °C, in hydrogen (H2) at different temperatures. It was demonstrated that the phase configurations, microstructures and magnetic properties of the as-deoxidized samples closely depended upon the...

Objective: The aims of this study were to investigate the release of element from, and the biological response in vitro to, cobalt-chromium alloys and other base-metal alloys used for the fabrication of metal-ceramic restorations. Material and methods: Eighteen different alloys were investigated. Nine cobalt-chromium alloys, three nickel-chromium alloys, two cobalt-chromium-iron alloys, one pal...

Abstract An entirely femtosecond laser (fs-laser) based process for the production of stable, enlarged and alloyed nickel surfaces is presented. The allows use metal foils aqueous salt solutions as alloying element sources. We alloy iron from an source well molybdenum cobalt commercially available on mesh without further coating process. It shown that content surface structured with fs-laser de...

The classical casting material cast iron is experiencing a renaissance. High strength CGI or alloyed cast iron components are substituting previously used non-ferrous castings in automotive power train applications. The mechanical engineering industry has recognized the value in substituting forged or welded structures with stiff and light-weight cast iron castings. New products such as wind tu...

Iron and its alloy have been proposed as biodegradable metals for temporary medical implants. However, the formation of iron oxide and iron phosphate on their surface slows down their degradation kinetics in both in vitro and in vivo scenarios. This work presents new approach to tailor degradation behavior of iron by incorporating biodegradable polymers into the metal. Porous pure iron (PPI) wa...

The processes of melt formation were studied by methods optical and electron scanning microscopy. These occur during induction brazing a hard alloy to steel holder contact interaction low-melting (copper-zinc system alloy) refractory (iron-nickel) components the solders. It is shown that effect thermal magnetic-dynamic high-frequency electromagnetic field on composite solder how high-strength j...
