Thermal analysis and wear behavior of shell mold cast and graphite mold cast Mg-4Zn-(x)Zr alloys
(CSIC Consejo Superior de Investigaciones Cientificas, 2021)The grain refining effect of Zirconium (Zr) is known, nevertheless the effect of Zr amount and its effect on solidification and wear behavior of modified Mg-Zn alloys has not been adequately studied. Mg-4Zn-(x)Zr alloys ... -
Thermoluminescence properties of strontium doped magnesium tetraborate
(Elsevier, 2019)It is worth to continuous and systematic investigations related with magnesium tetraborate (MBO) due to its attractive candidate for dosimetric application. The study was done to develop new phosphor with adding strontium ... -
Time-thermo-dynamics of anti-Stokes and Stokes scattering and luminescence in 1-nm silicon nanoparticles: Toward an optical nanorefrigerator
(American Institute of Physics Inc., 2022)The thermodynamics of nanosystems is interesting, as they constitute the transition between the atomistic and solid states. This is empowered by the development of tools to manipulate individual atoms and perform atomistic ... -
Titanium carbide coating to improve surface characteristic, wear and corrosion resistance of spheroidal graphite cast irons
(Elsevier, 2022)In this study, titanium carbide (TiC) coatings were grown on the surface of a spheroidal graphite cast iron (SGI) via thermo-reactive diffusion (TRD) using powder-pack processing at 800 °C, 850 °C and 900 °C for 4 h. The ... -
TTribocorrosion behavior of boronized Co1.19Cr1.86Fe1.30Mn1.39Ni1.05Al0.17B0.04 high entropy alloy
(Elsevier, 2021)Boride layers were grown on the surface of a Co1.19Cr1.86Fe1.30Mn1.39Ni1.05Al0.17B0.04 high-entropy alloy (HEA) by boronizing at temperatures of 900, 950 and 1000 degrees C for 4 h using nanosized boronizing powders. ... -
Updated database, new empirical and theoretical values of average L shell fluorescence yields of elements with 23 <= Z <= 96
(Pergamon-Elsevier Science Ltd, 2020)In this paper, a summary of existing experimental data published in the period of time between 1954 and 2015 is reviewed and presented in a tabular form for average L shell fluorescence yields taken from different sources. ... -
WEDM machining of MoNbTaTiZr refractory high entropy alloy
(Elsevier, 2022)Refractory high entropy alloys (RHEAs) have shown great promise for a multitude of advanced engineering applications due to their high mechanical stability from cryogenic temperatures to 1600 °C. However, the low ductility ... -
Wet non-thermal integration of nano binary silicon-gold system with strong plasmonic and luminescent characteristics
(Amer Inst Physics, 2019)We report on a wet none thermal integration of the binary silicon-gold nano system. Instead of thermally based gas-solid procedures, we use charge exchange/injection-based procedures in a chemical wet environment. SEM and ... -
Wideband luminescence from bandgap-matched Mg-based Si core-shell geometry nanocomposite
(American Institute of Physics Inc., 2018)We use wet treatment to integrate red-luminescent Si nanoparticles with Mg-based wide-bandgap insulators Mg(OH) and MgO (5.7 and 7.3 eV respectively). In the process, Mg2+ is reduced on Si nanoparticle clusters, while ... -
Wire electric discharge machining and its effect on the surface finish of HfNbTaTiZr refractory high-entropy alloy
(Springer, 2023)Refractory high-entropy alloys (RHEAs) have high strength and hardness but limited plasticity at room temperature, making them challenging to process and shape using conventional techniques. In the current study, HfNbTaTiZr ...
