Modulation of Charge Transport at Grain Boundaries in SrTiO3: Toward a High Thermoelectric Power Factor at Room Temperature
(American Chemical Society, 2021)
Modulation of the grain boundary properties in thermoelectric materials that have thermally activated electrical conductivity is crucial in order to achieve high performance at low temperatures. In this work, we show ...
Effect of Lanthanum on mechanical and wear properties of high-pressure die-cast Mg-3Al-3Sn-3Sb alloy
(Walter de Gruyter GmbH, 2021)
In the present study, the effect of an La alloying element with different quantities (1, 3 and 5 wt.-%) on the microstructure, mechanical and dry sliding wear properties of Mg-3Al-3Sn-3Sb alloy was investigated. The wear ...
Microwave absorption performance of hexagonal nano boron nitride doped basalt fabric-reinforced epoxy composites
(Emerald Group Publishing Ltd., 2021)
Purpose: The purpose of this paper is to investigate the effect of doping element on the microwave absorption performance of hexagonal nano boron nitride (h-nBN)-reinforced basalt fabric (BF)/epoxy composites. A new type ...
Microstructure and mechanical properties of borided CoCrFeNiAl0.25Ti0.5 high entropy alloy produced by powder metallurgy
(Elsevier, 2021)
CoCrFeNiAl0.25Ti0.5 high entropy alloy alloys (HEA), produced by powder metallurgy were subjected to boriding to improve their mechanical properties. Sintering was carried out at 1200 degrees C for 2 h in Ar, and boriding ...
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 ...
M Shell Fluorescence Parameters of Pt, Au and Tl Compounds with Oxygen and Bromide
(Adıyaman University, 2019)
In this study, Mβα X-ray production cross-sections and average M-shell fluorescence yields were determined by using EDXRF at 5.96 keV for Pt, Au and Tl compounds. The photo-peak areas were used for the measurement of M ...
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 ...
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. ...
A Novel and Eco-friendly Approach for the Simultaneous Recovery of Copper and Diamond from Waste Cutting Segments via Electrodissolution/Deposition
(Springer, 2021)
A new approach is brought to diamond recovery from waste cutting segments. Unlike the commonly used hydrometallurgical processes, this approach offers the simultaneous recovery of copper with diamond. Besides, instead of ...
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 ...
