Investigating the formation mechanisms of cu0.83si0.17 intermetallic phase formed at Cu-Si and Cu-(5at%)Nb/Si interfaces Güler, Hüsniye; Özenbaş, Ahmet Macit (2011-07-12) A study of intermetallic compound formation at the interface between copper thin film and silicon substrate is presented in this work. Two systems; Cu/Si and Cu-(5at%) Nb/Si, were studied. From the intermetallics formed at the interfaces of two systems; as a model, formation mechanisms of Cu0.83Si0.17 with and without niobium impurity were examined. Variations in values of parabolic rate constants and activation energies with Nb impurity content were determined. The samples were annealed at different temper...
Investigating the dominant factors regarding ignition transient in the design procedure of the nozzle of a pyrogen igniter Yeşilyurt, Yavuz; Güvenç Yazıcıoğlu, Almıla; Department of Mechanical Engineering (2019) In a standard solid rocket motor (SRM) system, the propellant of the SRM is generally ignited by a pyrotechnic device (which is much smaller in size compared to SRM itself). However, grand systems like solid propellant Space Propulsion Systems need more mass flow rate in a very short time duration to be ignited, which is not easy task for a pyrotechnic igniter. The solution for this issue is utilizing pyrogen igniter in the SRM system, which is both a small-scale SRM and an igniter. Here ignition transient ...
Investigating the effect of initial COD, VSS and pH to improve dark fermentative hydrogen production from sucrose and molasses Tunçay, Güneş; Bayramoğlu, Tuba Hande; Eroğlu, Inci; Gündüz, Ufuk (2014-05-07)
Investigating the effects of climate change on the surface runoff potential over Kızılırmak basin Barkış, Numan Burak; Yılmaz, Mustafa Tuğrul; Department of Civil Engineering (2022-9-2) The aim of this study is to analyze the expected change in the surface runoff potential that will occur due to climate change in the Kızılırmak Basin until 2100. HBV hydrological model was run in this study to investigate the expected change in 3 sub-basins (SB 1535, SB 1541, and SB 1545) of Kızılırmak Basin. Total of 56 CMIP5-based GCM/RCM daily model datasets, downloaded from CORDEX EUR-11 at 0.110 spatial resolution and reflect RCP 8.5 emission scenario, were utilized. Among these model datasets, 10 of t...
Investigating the reliability of ultrasound phased array method and conventional ultrasonic testing for detection of defects in austenitic stainless steels Akgün, Bahadır; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2015) In recent years Phased Array (PA) method has become an alternative to the conventional ultrasonic method for critical tests in aerospace, oil, gas and nuclear industries. There is a challenge for inspection of austenitic stainless steels due to high attenuation, skewing and scattering of sound beam. The aim of this thesis is to investigate and to compare the flaw detection abilities of conventional ultrasonic and PA systems using the probability of detection (PoD) approach for testing of austenitic stainles...
