Continuous synthesis of graphite with tunable interlayer distance
(Elsevier Science Sa, 2019)
A study was carried out to produce graphite with controlled interlayer distance synthesized from methane using hydrogen as modifying agent. The synthesis was carried out in radio frequency (r.f.) thermal plasma where the ...
Effect of Al doping on the magnetic and elastic properties of Fe65Ni35 Invar alloys
(Scientific Technical Research Council Turkey-Tubitak, 2019)
Invar alloys have great importance due to their low thermal expansion coefficient. The effect of Al doping on Fe65Ni35 Invar alloy was investigated by temperature-dependent magnetization and elastic modulus measurements. ...
Corrosion of magnesium alloy AZ31 screws is dependent on the implantation site
(Elsevier Science Bv, 2011)
The corrosion of biodegradable materials is a crucial issue in implant development. Among other materials, magnesium and magnesium based alloys are one of the most promising candidates. Since the corrosion of biodegradable ...
Mechanical characterization of highly porous beta-Si3N4 ceramics fabricated via partial sintering & starch addition
(Elsevier Sci Ltd, 2013)
In this study, porous beta-Si3N4 ceramics containing limited amount of Sm2O3 and CaO as sintering aids were produced by addition of potato starch (10 and 20 vol.%) and partial sintering. Two different Si3N4 powders, alpha- ...
Shell-ferromagnetism in a Ni-Mn-In off-stoichiometric Heusler studied by ferromagnetic resonance
(Amer Inst Physics, 2017)
Next to the multifunctional properties of Ni-Mn-based Heusler alloys new functionalities related to shell-ferromagnetism are emerging. To understand in more detail the properties of shell-ferromagnetism we examine a ...
Shell-ferromagnetism of nano-Heuslers generated by segregation under magnetic field
(Nature Publishing Group, 2016)
We report on a new functional property in an AF martensitic Heusler Ni50Mn45In5, which when annealed at high temperatures under a magnetic field, segregates and forms Ni50Mn25In25 Heusler precipitates embedded in a Ni50Mn50 ...
Exchange bias caused by field-induced spin reconfiguration in Ni-Mn-Sn
(Amer Physical Soc, 2016)
Exchange bias is observed in ferromagnetic/antiferromagnetic (FM/AF) layered stacks and in materials with neighboring ferromagnetic and antiferromagnetic granules. The latter is commonly observed in Ni-Mn-based martensitic ...
Large magnetocaloric effects in magnetic intermetallics: First-principles and Monte Carlo studies
(E D P Sciences, 2015)
We have performed ab initio electronic structure calculations and Monte Carlo simulations of frustrated ferroic materials where complex magnetic configurations and chemical disorder lead to rich phase diagrams. With lowering ...
Shell-ferromagnetism in Ni-Mn-based Heuslers in view of ductile Ni-Mn-Al
(Amer Inst Physics, 2017)
The presentwork deals with magnetic and structural phase instabilities in Ni-Mn-based Heusler alloys especially Ni-Mn-Al. The temper-annealed Ni50Mn45Al5 Heusler alloy decomposes into the full stoichiometric Ni2MnAl and ...
Fabrication and characterization of SmCo5/Nb ferromagnetic/superconducting hybrid thin films grown by RF magnetron sputtering technique
(Pergamon-Elsevier Science Ltd, 2017)
Ferromagnet/Superconductor (F/S) bilayer hybrids show exclusive states due to the mutual interaction between the superconductor and the underlying ferromagnetic substructures in micron scale. In this work, we aimed to ...
