AB  - Kinetics and mechanism of hydrogen adsorption in as-obtained and ground nuclear graphite
Wendelstein 7-X are examined. In the first time interval the adsorption process is determined
by dissociation of the hydrogen molecule, occurring at the outer surface and in open
micropores of nuclear graphite particles. However, in the second time interval, the slowest
step in the hydrogen adsorption is inter-granular and inter-crystallite diffusion in nanopores
of graphite. The X-ray analysis shows, that grinding of as-obtained nuclear graphite results in
finer particles with finer nanocrystals and larger density of opened pores and carbon reactive
sites. The capacity and rate of adsorption increase with comminution of nuclear graphite particles and adsorbed hydrogen does not sub stantially alter the microstructure of nuclear
graphite.

AB  - Nanostructured Ni-Fe-W-Cu alloy powders were electrodeposited from an alkaline ammonium citrate solution on a titanium cathode. Powder particles were dendrite- and cauliflower-shaped. The dendritic particles had a high density of branches made up of interconnected globules. XRD analysis showed that the powder contained an amorphous matrix and FCC nanocrystals of the solid solution of Fe, W and Cu in Ni. As the deposition current density increased, the mean nanocrystal size decreased, and the mean value of internal microstrain and the total weight percent of Fe and Ni in the alloy increased. The powders deposited at higher current densities exhibited higher magnetization. During annealing at temperatures up to 460 °C, the powders underwent short-range ordering, which caused an increase in magnetization, whereas at temperatures above 460 °C, the magnetization decreased due to the formation of large FCC crystalline grains.

AB  - A nanostructured powder of the Ni86,0Fe9,8W1,3Cu2,9 alloy is deposited on a titanium cathode by electrodeposition from the citrate bath, at the current density of 400 mA cm−2. The powder particles are of a cauliflower and dendritic shape and composed of nanocrystals of the FCC phase of the solid solution of iron, tungsten and copper in nickel, captive in an amorphous matrix. The freshly deposited powder is thermally stable up to 160 °C. The annealing of the powder in the temperature range from 160 °C to 460 °C results in its structure relaxation. At temperatures higher than 460 °C, the amorphous phase in the powder is crystalizing and crystal grains of the FCC solid solution are growing. The structural changes caused by annealing, affect magnetic properties of the alloy. The cooled powders after the structure relaxation have higher magnetization, a lower loss of the active power and a lower coercive field. Crystallization of the amorphous phase and crystalline grain growth of the FCC phase causes a decrease in magnetization, an increase in the power loss and the power of coercive field.

AB  - Ni-Fe-W-Cu alloy powders were obtained by electrodeposition from an ammonium citrate bath at current densities ranging between 70 and 600 mA cm-2. As the deposition current density increased, the contents of Fe and W in the alloy increased, and those of Ni and Cu decreased. The total cathodic polarization curve was recorded, and partial polarization curves for Ni, Fe and W deposition and hydrogen evolution were determined. The current efficiency of alloy deposition was measured. The powders contained an amorphous matrix and FCC nanocrystals of the solid solution of Fe, W and Cu in Ni. At high current densities, small-sized nanocrystals exhibiting high internal microstrain values were formed. Powder particles were dendrite-and cauliflower-shaped. The dendrites had a large number of secondary branches and higher-order branches containing interconnected globules. The density of branches was higher in particles formed at high current densities. The powders formed at high current densities exhibited higher magnetization. Annealing at temperatures up to 460 °C resulted in structural relaxation, accompanied by an increase in magnetization. At temperatures above 460 °C, amorphous matrix crystallization and FCC crystal growth took place, accompanied by a decrease in magnetization.

AB  - The thermal electromotive force (TEMF) and the thermal electromotive force coefficient (TEMFC) of the thermocouple consisting of a copper wire and an (X5CrNi1810) steel wire plastically deformed under tension or bending conditions were found to increase with increasing degree of plastic deformation. The increase in the degree of deformation disturbs the microstructure of steel due to increases in the density of chaotically distributed dislocations and internal microstress, resulting in a decrease in the electron density of states near the Fermi level. Through the effect of thermal energy, annealing at elevated temperatures up to 300°C leads to microstructural ordering along with simultaneous increases in the free electron density of states, TEMF and TEMFC. Based on the temporal change of the TEMF, the kinetics of microstructural ordering was determined. During the initial time interval, the process is a kinetically controlled first-order reaction. In the second time interval, the process is controlled by the diffusion of reactant species.

AB  - The hydrogenation of a crystalline Ni-Fe (80 wt.% Ni, 20 wt.% Fe) powder mixture leads to the formation of a mixture of Face Centered Cubic (FCC)-Ni and FCC-Fe phase nanocrystals embedded in an amorphous matrix. The magnetic susceptibility of the nanostructured powder is 2.1 times higher than that of the as-produced crystalline mixture. Heating in the temperature range 420-590 K causes structural relaxation in the hydrogenated powder, resulting in an increase of the magnetic susceptibility and a decrease of the electrical resistivity. During the heating procedure, the reorientation of magnetic domains in nickel and iron takes place in the temperature range 580-650 K and 790-850 K, respectively. In the pressed sample from the powder mixture, the crystallization of the amorphous phase of nickel and its FCC lattice crystalline grain growth occurs in the temperature range 620-873 K causing a decrease in the magnetic susceptibility of the nickel FCC phase and a sudden drop in the electrical resistivity. Prolonged heating of the mixed powders at 873K results in the formation of a Ni-Fe solid solution with higher magnetic susceptibility than the starting mixture.

AB  - Mechanism and kinetics of the thermally activated processes of the occurring by annealing of cold pressed samples of Cu-Al2O3 powder. With electrical resistance measurements in non-isothermal and isothermal conditions and with microstructural analysis, the influence of Al2O3 and temperature on the sintering process of Cu(1-x)-Al2O3(x) powders was determined. By measuring the isothermal change of specific electrical resistance at temperatures below the recovering temperature (400–680 K), the kinetics parameters of the process are determined. The sintering was performed in hydrogen at the temperatures of (1073, 1173, 1273) K for (15, 30, 60, 120) min. The results show that with increasing Al2O3 content the sintering time increases at all the examined

AB  - U cilju proučavanja strukturnih transformacija, kao i mehanizma i kinetike
termički aktiviranih procesa stabilizacije neravnotežne strukture kod hladno
sinterovanih uzoraka sistema Cu-Al2O3 sa 5, 10 i 15% disperzoida, izvršeno je
ispitivanje izotermske zavisnosti specifičnog električnog otpora od vremena. Merenjem
specifičnog električnog otpora u izotermskim uslovima na temperaturama nešto nižim
od temperature oporavljanja (450-650K), određeni su kinetički parametri i energija
aktivacije procesa oporavljanja uzoraka presovanih pod pritiskom od 100MPa. Pri tome
se došlo do zaključka da se proces oporavljanja odvija u dva stadijuma. Pored ovoga,
eksperimentalni rezultati pokazuju da sa porastom sadržaja Al2O3 konstanta brzine
odgovorna za promenu specifičnog električnog otpora, za oba stadijuma opada, a
energija aktivacije odgovarajućih procesa raste. Analiza mikrostrukture sinterovanih
uzoraka pokazuje da efekat poroznosti ima značajan uticaj na vrednosti specifičnog
električnog otpora, kao mere strukturne stabilizacije sistema. Takođe, analiza
mikrostrukture ukazuje na korelaciju promene specifičnog električnog otpora i rasta
zrna. Tačnije, rast zrna, usled smanjenja ukupne površine granica, pokazuje smanjenje
specifičnog električnog otpora sinterovanih uzoraka.
