Experimental Verification of Cell Shape-Collapse Relationships in Metallic Foams by Photoelasticity Method
(Gazi University, 2019)
In the present study, the effect of cell morphology on mechanical properties in metallic foams with Al based closed cells was examined. AlSi8Mg0.8 alloyed metallic foam materials were produced by the Powder Metallurgy (PM) ...
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. ...
Proximal probe-like nano structuring in metal-assisted etching of silicon
(American Institute of Physics Inc., 2019)
We use silicon having multiple crystalline orientation domains and high metal doping in metal assisted chemical etching (MACEtch) in HF/H2O2. In device-quality silicon, MACEtch produces high-aspect ratio anisotropic (1-D) ...
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 ...
Microstructure and mechanical properties of borided inconel 625 superalloy
(Universidade Federal do Rio de Janeiro, 2017)
The Ni-based superalloy Inconel 625 is extensively used owing to its high strength, excellent fabricability, good weldability and outstanding resistance to high temperature corrosion against aggressive environments. However, ...
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 ...
Boride Layer Growth Kinetics Of Aisi H13 Steel Borided With Nano-Sized Powders
(Polish Academy Sciences, Institute Metallurgy & Materials Sciences, 2018)
Growth kinetics of boride layers in AISI H13 steel was investigated using the pack bonding method at temperatures of 1073, 1173 and 1273 K (800 degrees C, 900 degrees C and 1000 degrees C) for periods of 2, 4 and 6 h with ...
Iron oxide-Si nanoparticle magnetic core-shell induced by the interaction of d-orbitals of Fe2+ with reconstructed Si dimer-like defects
(American Institute of Physics Inc., 2020)
Redox-type charge exchange between Si nanoparticles and aqueous metal ions m(x+) was recently used to synthesize core-shell nanocomposites in which their functionalities have been integrated. The process requires the ...
Determination of Barreling of Aluminum Solid Cylinders During Cold Upsetting Using Genetic Algorithm
(UNIV FED RIO DE JANEIRO, LAB HIDROGENIO, 2019)
This study presents Genetic Programming models for the formulation of barreling of aluminum solid cylinders during cold upsetting based on experimental results. The maximum and minimum radii of the barreled cylinders having ...
The Semi-Empirical Determination of Kα X-ray, KLL Auger Line and L subshell level widths for 3d transition elements at 59.5 keV
(Celal Bayar Üniversitesi, 2019)
The emission of X-rays in Ka and KLL Auger energy regions were analyzed for transition metals by using energy dispersive X-ray fluorescence (EDXRF) system. To acquire more information in this energy region, the semi-empirical ...
