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 spacing using a research-based empirical relation from the literature. Experiment results revealed that at the tip region of the cast specimen in the copper wedge-shaped mold, the carbide size was 7-8 mu m, where the solidification rate was approximately 4,830 degrees C.s(-1). The greatest carbide size obtained in the upper region of the sand cast wedge-shaped specimen was 250-270 mu m.

Effect of (Mo, W) substitution for Nb on glass forming ability and magnetic properties of Fe-Co-based bulk amorphous alloys fabricated by centrifugal casting Kucuk, Ilker; Aykol, Muratahan; Uzun, Orhan; Yıldırım, Mehmet; Kabaer, Mehmet; Duman, Nagehan; Yilmaz, Fikret; Erturk, Kadir; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (Elsevier BV, 2011-02-03) 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) ...
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 cyclic thermal loading on the performance of steel H-piles in integral bridges with stub-abutments Dicleli, Murat (Elsevier BV, 2004-02-01) In this paper, analytical equations are developed to estimate the lateral displacement capacity of steel-H piles in integral bridges with stub abutments subjected to cyclic thermal variations. First, steel H piles that are capable of sustaining large plastic deformations are identified based on their local buckling strength. The normalized moment-curvature relationships of these piles are then obtained for various axial load levels. Next, a low-cycle fatigue damage model is employed to determine the maximum...
Effect of spraying rate on microstructure of spray deposited Al-Fe-V-Si alloy Kalkanlı, Ali (Informa UK Limited, 2003-12-01) In this study gas atomisation and spray deposition of a series of AlFeVSi alloys were carried out. Traces of transient liquid were observed as lamellar structure in the middle of the specimen. The heat transfer conditions of this structure were modelled by finite difference calculation. Metallographic specimens for optical microscopy were prepared from the preforms formed in these processes. Optical microscopy showed the presence of dispersoids in the specimens. The dispersoids were characterised as AlFeVSi...
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 ...
