Abstract Wodegongjieite occurs in the Cr-11 chromitite orebody of Luobusa ophiolite Kangjinla district, Tibet, China. It is found two inclusions corundum: (1) as a partial overgrowth (holotype) up to 1.5 μm thick around spheroid 20 across wenjiite (Ti 10 (Si,P,□) 7 ), kangjinlaite 11 (Si,P) zhiqinite (TiSi 2 ) and badengzhuite (TiP), (2) pools 0.25 wide filling interstices between wenjiite, jin...

The stability of Nd(Fe,T)12 and the site preference of ternary elements T (T = Ti, V, Cr, Si) are investigated by using pair potentials based on ab initio method and lattice inversion technique. The calculated lattice parameters are found in good agreement with the values deduced from experiments. The calculated results show that either V, Ti or Cr makes the cohesive energy decrease markedly, i...

The effects of six particulate metals (Al, Ti, Zr, Nb, Ta and Cr) on cell viability and alkaline phosphatase (ALP) activity were studied in vitro using two types of osteoblast-like cells, MG-63 and HOS cells. The cell viability in the presence of Al, Ti and Zr was depressed at lower concentrations than in the presence of Nb, Ta and Cr. The average sizes of the Al, Ti, Zr, Nb, Ta and Cr particul...

OBJECTIVE To compare the deflection load characteristics of homogeneous and heterogeneous joints made by laser welding using various types of orthodontic wires. MATERIALS AND METHODS Four kinds of straight orthodontic rectangular wires (0.017 inch × 0.025 inch) were used: stainless-steel (SS), cobalt-chromium-nickel (Co-Cr-Ni), beta-titanium alloy (β-Ti), and nickel-titanium (Ni-Ti). Homogene...

In fulfilling the aims of planetary and asteroseismic research missions, such as that NASA Transiting Exoplanet Survey Satellite (TESS) space telescope, accurate stellar atmospheric parameters a detailed chemical composition are required input. We have observed high-resolution spectra for all 848 bright (V<8 mag) stars cooler than F5 spectral class in area up to 12 deg surrounding northern TESS...

In this work (Ti,Si,Al)N films were deposited using only rf or a combination of rf and d.c. reactive magnetron sputtering. Chemical composition, thickness, film structure and mechanical properties of the films were investigated by means of Rutherford backscattering (RBS), electron microprobe analysis (EPMA), ball-cratering, X-ray diffraction (XRD) and ultramicroindentation, respectively. All sa...

The present study investigates the influence of Si on high-temperature corrosion behavior lean FeCrAl model alloys in O2 and O2+H2O at 600 °C. addition prevented breakaway oxidation which may be explained by increased Al-content reduced Cr-content oxide (O2) as well Si-enrichment outer part scale (O2+H2O). A proposed explanation for impact Si-addition Cr- was given thermodynamic calculations sh...
