Effect of temperature on fatigue properties of Din 35 NiCrMoV 12 5 steel
Önem, Orkun Umur; Gürbüz, Rıza; Department of Metallurgical and Materials Engineering (2003)
DIN 35NiCrMoV125 (equivalent to AISI 4340), which is a high strength low alloy steel (HSLA), is mainly used at military applications in the production of gun barrels. The main aim of this study was to determine the low cycle fatigue (LCF) behaviour and the influence of temperature on low cycle fatigue failure properties of that steel. Three different temperatures (room temperature, 2500C and 4000C) were used in the experiments in order to analyze the effect of temperature. For each temperature, five strain ...
Effect of Thickness on Magnetic Properties of Fe36Co36B19.2Si4.8Mo2W2 Thin Film Prepared by Thermionic Vacuum Arc
Perincek, F.; Erturk, K.; AYKOL, M.; Kucuk, I.; Akdeniz, Mahmut Vedat (Institute of Physics, Polish Academy of Sciences, 2012-01-01)
Fe36Co36B19.2Si4.8Mo2W2 amorphous thin films have been produced by thermionic vacuum arc with thickness varying from 200 nm to 260 mn. X-ray diffraction has been employed to reveal a predominant amorphous phase in the as-prepared samples, although a small crystalline fraction cannot be excluded. The bulk magnetic properties of thin films were examined at room temperature using an ADE Magnetics EV9 vibrating sample magnetometer with maximum magnetic field strength of 1750 kA/m, real-time field control and dy...
Effect of heat transfer on stability and transition characteristics of boundary-layers
Özgen, Serkan (Elsevier BV, 2004-10-01)
Stability and transition problems of two dimensional boundary-layers with heated walls have been studied numerically using the linear stability theory. Incompressible stability equations have been modified to account for the variation of temperature dependent fluid properties across the layer. The equations obtained have been solved with an efficient shoot-search technique. Low speed flows of air and water have been analyzed with a wide range of heat transfer rates. In addition to the mean velocity profile ...
Effect of fiber type and concrete strength on the energy absorption capacity of fiber reinforced concrete plates under quasi-static bending
Mercan, Ali Macit; Yaman, İsmail Özgür; Department of Civil Engineering (2019)
With all the known solid advantages of concrete, it has also limitations in its mechanical properties, such as low ductility, tensile strength and energy absorption capacity/toughness. In order to eliminate or minimize these limitations, some developments have been worked up by introducing natural or artificial fibers into the concrete mixture. The main scope of this thesis is to observe the effect of different fiber types and dosages on the performance of two different concrete grades. Two steel fibers wit...
Effect of Electrodeposition Parameters on the Current Density of Hydrogen Evolution Reaction in Ni and Ni-MoS2 Composite Coatings
Gueler, E. Saraloglu; KONCA, ERKAN; Karakaya, İshak (2013-04-01)
Nickel composites with co-deposited insoluble, solid lubricant particles such as MoS2 have been reported to reduce friction. It is known that hydrogen evolution reaction (HER), competes with nickel deposition. The influence of the parameters and their interaction effects on the peak current density of HER during the electrodeposition of Ni and Ni-MoS2 composite coatings were studied by fractional factorial design. The parameters and their ranges studied were; MoS2 particle concentration (0-30 g/l), temperat...
