Semi analytical study of stress and deformation analysis of anisotropic shells of revolution including first order transverse shear deformation
Oygür, Özgür Sinan; Kayran, Altan; Department of Aerospace Engineering (2008)
In this study, anisotropic shells of revolution subject to symmetric and unsymmetrical static loads are analysed. In derivation of governing equations to be used in the solution, first order transverse shear effects are included in the formulation. The governing equations can be listed as kinematic equations, constitutive equations, and equations of motion. The equations of motion are derived from Hamilton’s principle, the constitutive equations are developed under the assumptions of the classical laminatio...
PSEUDOPOTENTIAL CALCULATION OF ATOMIC PAIR INTERACTION ENERGIES AND ESTIMATION OF THE KURNAKOV TEMPERATURE OF TERNARY ALLOYS Ni//3(Fe, Me).
Mehrabov, Amdulla; Babayev, Z.M.; Katsnel'son, A.A.; Matysina, Z.A. (1986-12-01)
The atomic pair interaction energy and Kurnakov temperature of ternary alloys Ni//3(Fe, Me) (Me equals Cr, Mn, W or Mo) are calculated using the Animalu pseudopotential. The calculated values of the Kurnakov temperature are in qualitative agreement with experimental results. A correct concentration dependence of the Kurnakov temperature for Ni//3(Fe, Me) alloys can only be obtained if ferromagnetism of those alloys is taken into account.
Nondestructive investigation of the effect of quenching and tempering on medium-carbon low alloy steels
Gür, Cemil Hakan (2005-01-01)
The aim of the study is to investigate the effect of quenching and tempering on sound velocity of steels, and to contribute to the nondestructive control and optimisation of the quenching/tempering systems. Disk-shaped specimens were prepared from AISI/SAE 4140 and AISI/SAE 5140 steel bars. All specimens were austenised and quenched identically to eliminate the effect of grain size on sound velocity, and a constant tempering time was chosen. Microstructures of the samples were characterised by metallographi...
Nondestructive evaluation of the effects of carburizing process parameters on microstructure and residual stress state of SAE 9310 steel via magnetic Barkhausen noise method
Yıldırım, Zafer; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2022-2-11)
Carburizing is a surface treatment process applied for improving the surface hardness, wear resistance, and also fatigue life of some critical aerospace and automotive components, such as gears, bearings, and bushings. It consists of carbon diffusion into low-C steels in the austenitized condition which results in a carbon gradient along with the depth, then followed by quenching, sub-zero treatment, and tempering. In a carburized component, a strong and wear-resistant surface layer (the case) with compress...
Non-equilibrium molecular dynamics of electromigration in aluminum and its alloys
Şen, Fatih Gürçağ; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2006)
With constant miniaturization of integrated circuits, the current densities experienced in interconnects in electronic circuits has been multiplied. Aluminum, which is widely used as an interconnect material, has fast diffusion kinetics under low temperatures. Unfortunately, the combination of high current density and fast diffusion at low temperatures causes the circuit to fail by electromigration (EM), which is the mass transport of atoms due to the momentum transfer between conducting electrons and diffu...
