Effect of temperature on band gap of PbWO4 single crystals grown by Czochralski method



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...

The effects of build orientation on the crack propagation behavior of Ti6Al4V fabricated by elecron beam melting which is one of metal additive manufacturing methods were examined in this study. Firstly, Ti6Al4V blocks were manufactured at different building angles (00,300,450and 900) regarding as base plane using EBM. Subsequently, test specimens were machined from these blocks in compliance with ASTM E8, ASTM E399 and ASTM E647 standards for tensile, fracture toughness and crack growth rate specimen...
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...
Effect of Illumination Temperature on Thermally Stimulated Current Spectrum of TlInS2
Özdemir, Salahattin; Bucurgat, Mahmut; Bulur, Enver (1999-01-01)
The effect of pre-illumination on both thermally stimulated current and photocurrent spectra of TlInS2 crystal is investigated. The increase in the photosensitivity of the crystal by several orders of magnitude together with the appearance of a new peak in the thermally stimulated current spectrum are observed as a result of the pre-illumination process. The filling of the traps, especially the sensitizing centers, during the pre-illumination is found to be the most favourable physical mechanism to explain ...
