A ZrAlCo ternary alloy was investigated in order to clarify the glass-forming ability, thermal stability and mechanical properties. The Zr 55 Al 20 Co 25 alloy was found to be fabricated in
2 days ago · Mechanical behavior of the samples was examined, and the resulting engineering stress vs. engineering strain curves are depicted in Fig. 4. The value of ultimate tensile strength (UTS), ductility and yield stress were extracted from this figure and are summarized in Fig. 4. As it can be deduced from this figure, nearly all the mentioned Effect of Zr on microstructure and oxidation behavior of The oxidation behavior of Ti-Al-Nb-Zr and Ti-Al-Zr ternary alloys was investigated to understand the effect of Zr on oxidation behavior at 1023 K. It was found that Zr improves the oxidation resistance of the phase more effectively than Nb. TiO2 was formed in all tested alloys. The addition of Zr drastically decreased the growth rate of TiO2.
The effects of boron and zirconium contents from 0 to 0.049 wt% on the casting fluidity, as-cast microstructure and mechanical properties of IN718C superalloy are systematically investigated. The results show that as the B or Zr content increases, the Influence of microstructure and mechanical properties Influence of microstructure and mechanical properties on the tribological behavior of reactive arc deposited Zr-Si-N coatings at room and high temperature K.

Their respective microstructures, elevated-temperature (600-1,000 C) mechanical properties, and thermal expansion behavior were then investigated. All the alloys are characterized by a Microstructure and Oxidation Behavior of CrAl Laser Microstructure and Oxidation Behavior of CrAl Laser-Coated Zircaloy-4 Alloy Jeong-Min Kim 1,*, and fairly good mechanical properties. However, Zr alloys are the Zr substrate was observed to be effectively restricted by the Cr coating layer during the oxidation.
Hv 0.01 4100) and adhesive strength (max. > 200 N) of the bilayer films are superior to those of the (Ti,Al,Zr)N and (Ti,Al,Zr,Cr)N monolayer films. Now on home page ads Microstructure evolution of V2AlC coating on Zr substrate V2AlC coatings prepared by magnetron sputteringon a Zr substrates were irradiated with He ions to simulate the behavior of accident tolerant fuels (ATFs) in a reactor. TEM analysis and scratch test showed that the He bubbles preferentially nucleated along the substrate-coating interface and resulted in a loss of mechanical resistance of the
Severe plastic deformation can be produced by repetitive upsetting-extrusion process. Using the repetitive upsetting-extrusion (RUE) process at decreasing temperature, the Mg-12.0Gd-4.5Y-2.0Zn-0.4Zr (wt %) alloy was deformed by different RUE passes and then heat treated. The microstructure, texture and mechanical properties of the alloy were compared and analyzed. Microstructure, mechanical property and corrosion behavior In this paper, biomedical porous Ti-Nb-Ta-Zr with 40% porosity and 166 ± 21 m macro-pore size was successfully fabricated by space holder method. The microstructure, Vickers hardness, compressive and electrochemistry behavior were studied. It results that a few second phases exist in matrix of th
In this study, the microstructure, mechanical properties, corrosion behaviors, and in vitro biocompatibility of Zr-Mo alloys as a function of Mo content after solution treatment were systemically investigated to assess their potential use in biomedical application. Structure and mechanical properties of Zr/TiAlN films The purpose of this study was to investigate the effects of Zr interlayer on the structure and mechanical properties of TiAlN films, which were deposited on the M2 high-speed steel substrates by means of plasma-enhanced magnetron sputtering. The result shows that the crystal orientation of Zr/TiAlN films is similar to that of single-layered TiAlN films, but the
