Local atomic structure in al-re marginal metallic glasses
Övün, Mert; Kalay, Yunus Eren; Department of Metallurgical and Materials Engineering (2016)
Partial devitrification of the Al-RE marginal metallic glasses results in anomalous nucleation rate of nanocrystals conflicting with the classical nucleation theory by several orders of magnitude. One of the theoretical approaches explaining this phenomenon is the medium-range order (MRO) structures within the range of 1-2 nm that may be present both in the quenched amorphous state and its liquid precursor. In this work, these structures have been investigated conducting both experimental methods such as hi...
Local energy losses at positive and negative steps in subcritical open channel flows
Tokyay, Nuray; Altan Sakarya, Ayşe Burcu (2011-01-01)
Local energy losses occur when there is a transition in open channel flow. Even though local losses in subcritical open channel flow due to changes in channel width have been studied, to date no studies have been reported for losses due to changes in bed elevations. Steps are commonly used in engineering applications to stabilise the flow in open channels. Hence, it is important to estimate local losses for design purposes. The aim of this study was to formulate the local energy losses at positive and negat...
Local structures of the Al-RE marginal metallic glasses and liquids: A molecular dynamics study

Al-based metallic glasses (MGs) have outstanding structural and functional properties and are of great interest in the literature and industry. The formation of metallic glasses opens up extraordinary possibilities, and the structure and structure-property relationship at the atomic level must be thoroughly studied to tailor such properties. Al-Rare Earth (RE)-based alloys form an important class of marginal glass-forming alloys in which the presence of Al nanocrystals accompanies primary crystallization. O...

In this study, the radial basis function (RBF) approximation is applied for solving the unsteady fluid flow and magnetohydrodynamic (MHD) convection flow problems with the use of explicit Euler time discretization and relaxation parameters to accelerate the convergence. The stability analysis is also carried out in terms of the spectral radius of related RBF discretized coefficient matrices. The optimal choices of the time increment, relaxation parameters and physical problem parameters are found for achiev...
