The effects of starting powder morphology on the thermal and mechanical properties of stand-alone plasma-sprayed 7 wt.% Y2O3-ZrO2 (YSZ) coatings were studied. Two powder morphologies were investigated: an agglomerated and sintered powder (referred to presently as "AS") and a powder manufactured using plasma spheroidization to create hollow spheres (referred to presently as "HS"). Coatings made from AS powders contained 0.21 wt.% SiO2 impurity, twice as much as observed in coatings made from HS powders. Properties of coatings made from each powder type were compared in the as-sprayed state and after 50 h heat treatments at temperatures ranging from 1000 to 1400 degrees C.

Effect of calcium or yttrium doping on cation ordering and electrochemical performance of Li(Ni0.80-xCo0.15Al0.05Mx)O-2 (M = Ca, Y) as a Li-ion battery cathode Uygur, Cansu Savas; Aydınol, Mehmet Kadri (Elsevier BV, 2021-02-01) The electrochemical performance of Li(Ni-0.80-xCo(0.15)Al(0.05)M(x))O-2 (NCA) cathode was demonstrated to be improved by calcium and yttrium doping. Samples were synthesized by ultrasonic sound-assisted co-precipitation method which satisfied precipitation of nano-sized particles around 20 nm. Doping elements were introduced to the structure by solid-state reaction route and single phase, layered Li-0.993(Ni0.804Co0.154Al0.035Y0.014)O-2 +/-sigma and Li-0.991(Ni0.801Co0.152Al0.037Y0.019)O-2 +/-sigma samples ...
Effect of Sm on thermal and mechanical properties of Cu-Zr-Al bulk metallic glasses Sikan, Fatih; Atabay, S. E.; Motallebzadeh, A.; Özerinç, Sezer; Kalay, I.; Kalay, Yunus Eren (Elsevier BV, 2019-01-16) The effect of rare-earth (Sm) microalloying on the thermal stability and phase selection along with the effect of nanocrystallization on the mechanical properties of amorphous melt-spun ribbons of Zr50Cu40Al10, Zr49Cu39.2Al9.8Sm2 and Zr48Cu38.4Al9.6Sm4 alloys were investigated using differential scanning calorimetry (DSC), X-ray diffraction (XRD), transmission electron microscopy (TEM), Vickers and nanoindentation hardness tests and micropillar compression analysis. XRD and TEM analyses showed that all samp...
Effect of tube spinning and subsequent heat treatments on strength, microstructure and residual stress state of AISI/SAE type 4140 steel Gür, Cemil Hakan (Informa UK Limited, 2003-11-01) In the present study, the effects of deformation percentage (23, 30, 50 and 66%) and subsequent stress relief and tempering heat treatments on the mechanical properties, residual stress state and microstructure of AISI/SAE type 4140 steel tubes manufactured by forward spinning were evaluated. Mechanical properties were determined by means of hardness and tensile tests. The tangential component of the surface residual stresses was determined by a slitting method. Plastic deformation of the metal during spinn...
Effect of Microstructure on the Mechanical Behavior of Reactive Magnetron Sputtered Al2O3/TiO2 Multilayer Ceramics Dericioğlu, Arcan Fehmi (Japan Institute of Metals, 2008-11-01) Mechanical characteristics of reactive magnetron sputtered Al2O3-TiO2 multilayer ceramics were studied. Tailored mechanical properties such as moderately high hardness and reasonable toughness were achieved through varying sputtering process parameters resulting in microstructural control at nano-scale. Interchanging Al2O3 and TiO2 layers with a single layer thickness of similar to 65-70 nm were deposited on single crystal alumina (sapphire) substrates to form the multilayer structure composed of 10 layers....
Effect of prolonged heating at 130 degrees C on fatigue crack propagation of 2024 Al alloy in three orientations Sarioglu, F; Orhaner, FO (Elsevier BV, 1998-06-15) An AI-Cu alloy 2024 received in T3 condition (cold worked after solutionizing and natural aging) was heated at 130 degrees C for 100 and 1000 h. Fatigue crack growth tests were carried out before and after heating with center cracked tension specimens machined in L-T, T-L and 60 degrees orientations. Fracture surfaces were studied by means of scanning electron microscopy. It was found that the fatigue crack growth rate depends on the test direction in T3 condition. The orientation effect seemed to be lost a...
