THE EFFECTS OF IMPURITY ELEMENTS ON THE PREFERRED ORIENTATION DURING MELT-SPINNING OF DILUTE ZN ALLOYS

The effects of aquifer heterogeneity on the natural attenuation rates of chlorinated solvents Önkal, Başak; Ünlü, Kahraman; Department of Environmental Engineering (2005) Monitored natural attenuation has been particularly used at sites where petroleum hydrocarbons and chlorinated solvents have contaminated soil and groundwater. One of the important aspects of the methodology that has been recognized recently is that the mass removal rates, the most important parameter to determine effectiveness of the methodology, is controlled by the groundwater flow regime and the aquifer heterogeneity. Considering this recognition, the primary objective of this study is to quantitatively...
Effects of air atomisation, spray deposition and melt overflow techniques on microstructural features of Al-Fe-V-Si alloy Kalkanlı, Ali; OZYURDA, HA (2005-09-01) Microstructural features of atomised powders, spray deposited preforms and melt overflow strips of 8009 series AlFeVSi alloy were investigated to reveal the microstructural evolution associated with the processing condition variations. X-ray diffraction (XRD), optical microscopy and scanning electron microscopy (SEM) techniques were used to identify the crystal structures of dispersoid phases in the specimens. The primary intermetallic phase was characterised as bee alpha-Al(Fe,V)Si having a lattice paramet...
The Effect of Mixture Parameters on the Surface Properties of Roller Compacted Concrete (RCC) Pavements Shabanı, Reza; Şengün, Emin; Öztürk, Hande Işık ; Yaman, İsmail Özgür (2021-09-01) In Turkey, the use of RCC pavements is increasing in urban and rural roads. However, a detailed study examining the effect of RCC mixture parameters on the pavement surface properties that affect road driving comfort and safety is not available in literature. In this study, in order to cover that gap in literature 12 RCC mixtures prepared with different cement dosages, aggregate gradations and water amounts were compacted by "Superpave-Gyratory-Compactor" at different levels. Later, the surface characterist...
The effect of infill walls on the seismic behavior of boundary columns in RC frames Fenerci, Aksel; Binici, Barış; Ezzatfar, Pourang; Canbay, Erdem; Ozcebe, Guney (2016-03-01) The seismic behavior of a 1/2 scaled, three-story three-bay RC frame with masonry infill walls was studied experimentally and numerically. Pseudo-dynamic test results showed that despite following the column design provisions of modern seismic codes and neglecting the presence of infill walls, shear induced damage is unavoidable in the boundary columns. A finite element model was validated by using the results of available one-story one-bay frame tests in the literature. Simulations of the examined test fra...
The role of nanoparticle geometry in flame retardancy of polylactide nanocomposites containing aluminium phosphinate Isitman, Nihat Ali; Doğan, Mehmet Onur; BAYRAMLI, ERDAL; Kaynak, Cevdet (2012-08-01) Although there is considerable research effort in the development of halogen-free flame-retardant polylactide (PLA), a bio-based aliphatic polyester, the potential synergistic interactions of nanoparticles and conventional additives have scarcely been considered. Therefore, this study aimed to investigate the influence of nanofiller geometry on fire retardancy of PLA nanocomposites containing aluminium diethylphosphinate (AlPi) flame retardant. For this purpose, a variety of nanofiller geometries were utili...
