In this study, effects of simultaneous Mo and W substitution for Nb additions on the stability and magnetic properties of Fe-Co-based bulk metallic glass (BMG) alloys fabricated by centrifugal casting are investigated. The saturation magnetization (J(s)) and coercivity (H(c)) for the as-cast Fe(36)CO(36)B(19.2)Si(4.8)X(4) (X = Nb or Mo(0.5)W(0.5)) BMG alloys and melt-spun Fe(36)Co(36)B(19.2)Si(4.8)Mo(2)W(2) were in the range of 1.02-1.57T and 11.13-1685 A/m, respectively. The Fe(36)Co(36)B(19.2)Si(4.8)X(4) (X = Nb or Mo(0.5)W(0.5)) BMG alloys in the shape of wedge with the maximum thickness of 1.5-2 mm were obtained successfully by means of conventional centrifugal casting. Replacing Nb with Mo(0.5)W(0.5) deteriorates magnetic properties in bulk form and reduces the GFA of the alloy due to promoting the precipitation of non-magnetic compounds, while it results in good soft magnetic properties in melt-spun ribbon form.

Effects of annealing temperature on the structural and optical properties of ZnO hexagonal pyramids
BACAKSIZ, EMİN; YILMAZ, ŞERİFE; Parlak, Mehmet; Varilci, A.; Altunbas, M. (Elsevier BV, 2009-06-10)
ZnO thin films were deposited on quartz substrate at 550 degrees C by using spray pyrolysis method and subsequently annealed between 600-900 degrees C with a step of 100 degrees C. The characterizations of the structural and optical properties of the films have been carried out by means of X-ray diffraction, scanning electron microscopy (SEM) and optical transmittance measurements. XRD ans SEM images indicated that annealing temperature did not play a great role on the microstructure of ZnO films. ZnO thin ...
Effect of vanadium on atomic ordering characteristics and anti-phase boundary energies of B2-FeCo alloys
AYKOL, Muratahan; Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (Elsevier BV, 2010-05-01)
Effect of V on the energetical and structural characteristics of atomic ordering processes of B2-FeCo intermetallics have been investigated via electronic theory of multi-component alloys combined with Monte Carlo (MC) simulations. Emphasis has been placed on the variation of anti-phase boundary (APB) energies with V content and temperature to establish a relationship between ductility and atomic ordering characteristics of (FeCo)(100-x)V(x) (x = 0-5 at%) alloys. It was shown that APB energies are highly af...
Effect of solidification rate on microstructure and primary carbides of AISI DC 53 cold work tool steel
Cardakh, Ismail Seckin; Kalkanlı, Ali (Springer Science and Business Media LLC, 2019-05-01)
The solidification behavior of AISI DC 53 cold work tool steel was investigated by means of a cooling curve and its first derivative. Copper and sand wedge-shaped molds were used to obtain various solidification rates. To reveal the cooling rate degree during solidification, the secondary dendrite arm spacing of the steel alloy was examined by scanning electron microscopy (SEM). The solidification rates of each section for both wedge steel samples were calculated by means of the secondary dendrite arm spaci...
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...
The structural and electronic properties of BN and BP compounds and BNxP1-x alloys
Mohammad, Rezek; Katırcıoğlu, Şenay (Elsevier BV, 2009-06-10)
The structural and electronic properties of BN and BP compounds and BNxP1-x alloys have been investigated by full potential linearized augmented plane wave (FP-LAPW) method based on density functional theory (DFT). The total energies and electronic band structures of these compounds have been calculated for different approximations of exchange-correlation energy. The comparative study has showed that the Perdew-Wang-generalized gradient approximation (PW-GGA) is the best one to produce the measured structur...
