Fractal Nature of Advanced Ni-Based Superalloys Solidified on Board the International Space Station
(Basel : MDPI AG, 2021)
Materials science is highly significant in space program investigation, energy production and others. Therefore, designing, improving and predicting advanced material properties is a crucial necessity. The high temperature ...
The structure analysis methods for synthetized diamonds consolidation and fractals characterization
(Belgrade : Serbian Society for MicroscopyBelgrade : Institute for Biological Research "Siniša Stanković", 2019)
Synthetized diamonds have application in many areas, especially for electronic devices and components or mechanisms in watches, and medicine where they can be used for surgery knifes. Considering that for small grains is ...
Niobium doping effect on BaTiO3 structure and dielectric properties
(Elsevier, 2020)
The effect of Nb on the microstructure and dielectric properties of BaTiO3 ceramics was investigated. The Nb/Mn–BaTiO3 ceramics were prepared using a conventional solid-state method. The concentration of Nb varied from 0.1 ...
Macro and Micro-Scale Features of Thermoelectric PbTe (Br, Na) Systems: Micro-FTIR Spectroscopy, Micro-Seebeck Measurements, and SEM/EDX Observations
(Springer, 2014)
In this work, n-type and p-type PbTe doped with Br and Na, respectively, were thoroughly examined to determine the effect of the dopant on microstructure. Macro and micro homogeneity of the samples were studied by means ...
The fractal nature approach in ceramics materials and discrete field simulation
(ETRAN, 2018)
In this paper, we present experimental data of static fractals and compare the results with theoretical analysis obtained using dynamic particle simulation. The fractal simulator presented in this manuscript is pioneer ...
Electrical properties and microstructure fractal analysis of magnesium-modified aluminium-silicate ceramics
(Belgrade : International Institute for the Science of Sintering, 2011)
The addition of Mg2(NO)3 and some active additives, composed of Al salts, to the mixtures of kaolinite and bentonite can provide clay compositions which, after sintering at high temperatures, produce very porous ceramics ...
Influence of MN doping on the evolution of microstructure and optical properties of mechanically activated SrTiO3 powders
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2022)
Manganese doped SrTiO3 powders with various manganese dioxide weight percentages in the range of 1.5, 3 and 6 wp% were prepared by a solid-state method in the presence of mechanical activation (10, 30 and 120 minutes). A ...
Mechanical activation and HIP of ZrB2-TIB2 based composites for hypersonic system
(Krakow : Agencja Reklamowa EURO GRAPHICKrakow : Polskie Towarzystwo Ceramiczne, 2022)
Ultra-high temperature ceramics, such as ZrB2, are convenient for application in hypersonic systems due to melting point higher than 3000 °C and excellent ablation resistance. For such application further improvement by ...
Elevated Temperature Thermal Properties of ZrB2 with Tungsten Additions
(Belgrade : University of Belgrade - Faculty of Mechanical Engineering, 2023)
The thermal properties of zirconium diboride (ZrB2) ceramics with tungsten additions of up to 5 wt% were characterized up to 2000°C. Densification was promoted by the addition of 0.5 wt% carbon. ZrB2 ceramics were prepared ...
Investigating on the microstructure and optical properties of Au, Ag and Cu implanted TiN thin films: The effects of surface oxidation and ion-induced defects
(Elsevier, 2024)
In the present paper, the effects of metal ion implantation on the structural and optical properties of TiN thin films have been investigated. TiN films of 170 nm thickness were grown by d.c. reactive sputtering on Si (100) ...
