Effect of Impurities on the Lattice Site Occupancy Characteristics of Ti-Al Intermetallics



Effect of bentonite composition on the HP, HT rheological properties of water-based drilling fluids
Kuru, E; Demirci, S; Ozturk, MY (1998-12-01)
In this study, effects of six bentonites on the viscosity and filtration loss characteristics of water-based drilling fluids have been investigated. Rheological properties of the drilling fluids prepared by API standards were determined by using high temperature (0-100 degrees C) rotational viscometer. The filtration losses of these drilling fluids were measured using high temperature (0-232 degrees C) and high pressure (0-2000 psi) filtration loss measurement equipment.
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 Ternary Alloying Elements Addition on the Order-Disorder Transformation Temperatures of B2-Type Ordered Fe-Al-X Intermetallics
Yıldırım, Mehmet; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (2012-06-01)
The effect of alloying element additions on B2a dagger"A2 order-disorder phase transformation temperatures of B2-type ordered Fe-0.5(Al1-n X (n) )(0.5) intermetallics (X = Cr, Ni, Mo, Ta, Mn, Ti, and W) that readily form single-phase solid solution for X = 1 at. pct were investigated experimentally. It was shown that the type of the ternary substitutional alloying elements have a profound effect on the variation of order-disorder transition temperature of Fe-0.5(Al1-n X (n) )(0.5) alloys. Based on the magni...
Effect of production parameters on porosity and hole properties in laser sintering rapid prototyping process
İlkgün, Özkan; Erdal Erdoğmuş, Merve; Department of Mechanical Engineering (2005)
Selective laser sintering (SLS) is a rapid prototyping method in which three-dimensional objects are constructed by sintering thin layers of a variety of powdered materials via laser beam. In SLS, as in most other Rapid Prototyping methods, the produced parts exhibit varying degrees of intrinsic porosity due to the discrete nature of layer-by-layer production. Selective scanning and discrete bonding of individual particles or clusters of particles impart local porosity, which is mostly an undesired trait as...
Effect of ternary alloying elements addition on atomic ordering characteristics of Fe-Al intermetallics
Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (Elsevier BV, 1999-05-28)
The energetic and structural characteristics of atomic ordering processes in Fe-0.5(Al1-nXn)(0.5) intermetallics have been qualitatively analyzed based on the statistico-thermodynamical theory of ordering by means of a quasi-chemical method combined with electronic theory in the pseudopotential approximation. The effects of ternary impurities on order-disorder phase transformation temperature and the characteristics of atomic short-range order in Fe-Al type intermetallics have been calculated. Impurity elem...
