Characteristics, high temperature wear and oxidation behavior of boride layer grown on nimonic 80A Ni-based superalloy
(Elsevier, 2021)
Nickel-based superalloy Nimonic 80A was pack-borided in a solid medium at temperatures of 850 degrees C and 950 degrees C for 2 h and 4 h using silicon-free boriding powders. To investigate the effects of the boriding ...
Detail investigation of thermoelectric performance and magnetic properties of Cs-doped Bi2Sr2Co2Oy ceramic materials
(Springer, 2021)
Bi2Sr2-xCsxCo2Oy materials with 0 <= x <= 0.15, have been fabricated via the classical ceramic technique. XRD results have indicated that undoped and Cs-substituted samples are composed of Bi2Sr2Co2Oy phase as the major ...
A Study on Analysis of Sinter Microstructure and Phase Morphology
(Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021)
Sinter is a blast furnace input material obtained by temperature to 900-1200 oC without full melting and adhering to each other with superficial melting. It is considered as a multi-phase material with its heterogeneous ...
Dynamic transition of nanosilicon from indirect to direct-like nature by strain-induced structural relaxation
(AIP Advances, 2021)
Silicon nanoclusters exhibit light emission with direct-like ns-mu s time dynamics; however, they show variable synthesis and structure, optical, and electronic characteristics. The widely adopted model is a core-shell in ...
Effect of thermal degradation on the properties and wear behavior of Cr−V−C composite coatings grown on ductile iron
(Elsevier, 2021)
The thermal fatigue behavior of chromium vanadium carbide (Cr - V - C) coatings and the wear of the coatings after thermal fatigue cycling was studied. The Cr - V - C coatings were grown on the surface of a ductile iron ...
Prediction of shrinkage ratio of ZA-27 die casting alloy using artificial neural network, computer aided simulation, and comparison with experimental studies
(Sharif University of Technology, 2021)
In cast alloys with a long freezing range such as ZA-27, casting defects like porosity and shrinkage may occur in case of failure to control casting variables. In this study, the role of casting variables in the formation ...
Microhydrogen production with water splitting from daily used waste aluminum
(Elsevier, 2021)
In this study, different types of waste aluminum produced in daily life and their pure equivalents were evaluated and compared in terms of their hydrogen generation performance through the water-splitting reaction. An ...
The investigation of microstructure and high temperature mechanical properties of novel Mg-Al-Sn-Ce alloy produced by HPDC
(Taylor and Francis, 2021)
Different weight ratios of cerium (0.5, 1 and 2 wt.%) were produced in a controlled atmosphere by High Pressure Die Cast method to Mg-6Al-0.3Mn-1Sn alloy. The influence of cerium on microstructure and high-temperature ...
Microstructure, some mechanical properties and tribocorrosion wear behavior of boronized Al0.07Co1.26Cr1.80Fe1.42Mn1.35Ni1.10 high entropy alloy
(Elsevier, 2021)
High-entropy alloys (HEAs) with face-centered cubic (FCC) structures exhibit high toughness and corrosion resistance, but their average strengths and relatively low wear resistance can limit their engineering ap-plications. ...
Polarization-based surface enhanced Raman scattering from single colloidal DNA decorated with 3 nm silicon nanoparticles
(American Institute of Physics Inc., 2021)
Surface enhanced Raman scattering (SERS), in which sample molecules are placed in the proximity of conducting nanostructures, subjects the molecules to intense electron oscillation (plasmon) field. The intense field, ...
