Interdiffusion coefficients of the refractory elements in Fe-W-Re and Fe-Cr-X (X=Mo, W) ternary alloys have been measured on the basis of the modified Boltzmann-Matano method for ternary system. Both the cross interdiffusion coefficients, Fe ReW ~D and Fe WRe ~D were negative in Fe-W-Re ternary alloys. This result indicates that attractive interaction exists between W and Re atoms in iron alloys [1]. This is consistent with our previous experimental results that Re suppresses W diffusion in Fe-15Cr alloy [1]. In addition, the value of cross interdiffusion coefficient Fe CrW ~D was positive in

Abstract The precipitation of supersaturated solutes at free surfaces in ternary Fe–3Au–4W and binary Fe–3Au and Fe–4W alloys (composition in weight percentage) for different ageing times was investigated at a temperature of 700 °C. The time evolution of the surface precipitation is compared among the three alloys to investigate the interplay between the Au and W solutes in the ternary system. The Au-rich grain-interior surface precipitates show a similar size and kinetics in the Fe–Au–W and Fe–Au alloys, while the W-rich grain-interior surface precipitates show a smaller size and a higher num

The results show that only the master alloy with high content of W (19.9 at.%) and B (13.6 at.%) of the six alloys studied yielded amorphous Fe-W-B powders. The alloying elements W and B are believed to have a glass-forming ability (GFA)-enhancing effect, which together with the high cooling rate of gas atomization leads to the formation of amorphi

Atomic redistribution of W and Fe in Si were studied using secondary ion mass spectrometry and transmission electron microscopy. W diffusion experiments performed during isothermal annealing and during Si oxidation show that W atoms should use at least two different diffusion mechanisms. Experimental diffusion profiles can be well simulated by considering the simultaneous use of three different W diffusion mechanisms: the dissociative and the kick-out mechanisms, as well as an original mechanism based on the formation of a W-Si self-interstitial pair located on the interstitial Si sub-lattice.

The leveling power of gluconate and citrate electrolytes used to obtain the Co-W and Fe-W alloys was studied. The leveling power parameter P was calculated according to the results of profilographic measurements of microprofile carried out before and after deposition of the coating on surface. It was shown that deposition of said alloys occurs with preferential coating thickness increase on microprofile peaks and low microlevelling power.

The electrodeposition of binary and ternary coatings Fe-W and Fe-Co-W from mono ligand citrate electrolyte has been investigated. The Fe-Co-W coatings were formed from electrolytes, which composition differs in the ratio of the concentrations of the alloying components and the ligand content. The investigation results indicate a competitive reduction of iron, cobalt and tungsten, the nature of which depends both on the ratio of electrolyte components, and electrolysis parameters. The effect of both current density amplitude and pulse on off time on quality, composition and surface morphology o

Celem pracy była ocena zawartości wybranych pierwiastków (Ca, Mg, Cu, Fe, Mn i Zn) w różnych rodzajach czekolad. Analizie poddano 20 czekolad, w tym: białe (B), mleczne (M) i gorzkie (G) o różnej zawartości masy kakaowej. Pogrupowano je według zawartości suchej masy kakaowej następująco [%]: G6 – 60, G7 – 70, G8 – do 85, G9 – 90. Suchą masę w próbkach oznaczono metodą suszarkowo-wagową. Oznaczenie zawartości Ca, Mg, Cu, Fe, Mn i Zn wykonano metodą płomieniowej atomowej spektrometrii absorpcyjnej (F-AAS) przy użyciu spektrometru AAS-3 Carl-Zeiss po uprzedniej mineralizacji próbek techniką spopi

In this study, Fe/TiO2 powder was synthesized by sol-gel method using mixture of Titanium Tetraisopropoxide (TTIP) as precursor and FeCl3 as iron source of 10% (w/w). The Fe/TiO2 powder was calcined at 500 °C for 1 hour. The sample of Fe/TiO2 was characterized using FTIR anad DRS measurements. FTIR analysis showed that Fe was successfully doped on TiO2 and then DRS analysis proved that the visible light was absorbed by Fe/TiO2 with its band gap energy up to 2.3 eV

The ferromagnetic properties of ultrathin films grown on non-magnetic substrates provide interesting new insights into the physics of magnetism. In this report we review experiments in the very low coverage regime (Θ < 2 atomic layers). The Fe monolayer on W plays an outstanding role, because it forms a ferromagnetic and thermodynamically stable monolayer. Ferromagnetic Fe monolayers on W can be prepared with a high degree of perfection. We therefore focus on ultrathin Fe films on W(110) and W(100) substrates. Experimental results for these in-plane magnetized films, prepared as close as po

Blended elemental W–7 wt.%Ni–3 wt. %Fe powders were mechanically alloyed in a planetary ball mill and a heavy duty attritor. The structural and morphological characteristics of the as-milled powders were characterized by x-ray diffraction and electron microscopy techniques. A ternary solid solution of Fe and Ni in W formed in both the cases; the amount of Ni and Fe dissolved is higher in the attritor-milled powder than in the ball-milled powder. Morphologically, the W-rich particles in the attritor-milled powders were spheroidal, smaller in size, and showed a narrower size distribution than in
