Low velocity impact characterization of monolithic and laminated AA 2024 plates by drop weight test
Kalay, Yunus Eren; Ögel, Bilgehan; Department of Metallurgical and Materials Engineering (2003)
The objective of this study was to investigate the low velocity impact behavior of both monolithic and laminated aluminum alloy plates. For this purpose, a drop-weight test unit was used. The test unit included the free fall and impact of an 8 kg hammer with an 8 mm punching rod from 0.5 m to 4 m. The relationship between the change in static mechanical properties (hardness, ultimate tensile strength, yield strength, strain hardening rate) and low velocity impact behavior of monolithic aluminum plates were ...
Screening of Protective Effect of Amifostine on Radiation-Induced Structural and Functional Variations in Rat Liver Microsomal Membranes by FT-IR Spectroscopy
Cakmak, Gulgun; Zorlu, Faruk; Severcan, Mete; Severcan, Feride (2011-04-01)
In this study, the protective effect of amifostine, which is the only FDA-approved radioprotective agent, was investigated against the deleterious effects of ionizing radiation on rat liver microsomal membranes at molecular level. Sprague-Dawley rats, which were either administered amifostine or not, were whole-body irradiated with a single dose of 800 cGy and decapitated after 24 h. The microsomal membranes isolated from the livers of these rats were investigated using FT-IR spectroscopy. The results revea...
Investigation of microstructural homogeneity and thermal stability of equal channel angular pressed and aged 2024 Al alloy
Kotan, Güher; Gür, Cemil Hakan; Kalay, Yunus Eren; Department of Metallurgical and Materials Engineering (2014)
Attributed primarily to its uniqueness, simplicity and ability for effective strengthening through grain refinement without reduction in cross sectional area, equal channel angular pressing (ECAP) has been known as one of the most important metal working process. The implementation of ECAP with precipitation hardening exhibits a promising strengthening mechanism to be applied to age-hardenable metals. On the other hand, the combined effect of precipitation hardening and excessive plastic strain is quite com...
Characterization of AgGa0.5In0.5Se2 thin films deposited by electron-beam technique
KARAAĞAÇ, HAKAN; KALELİ, Murat; Parlak, Mehmet (IOP Publishing, 2009-08-21)
AgGa0.5In0.5Se2 thin films were deposited onto a quartz substrate by the electron-beam technique. For the investigation of the annealing effect on structural, optical and electrical properties of deposited films, samples were annealed in the temperature range 300-775 degrees C. The composition analyses of the deposited films carried out by energy dispersive x-ray analysis measurements have shown that the deposited AgGa0.5In0.5Se2 films were indium- and gallium-rich but selenium-and slightly silver-deficient...
Production and characterization of maghemite nanoparticles
Baltacı, Özge Acarbaş; Özenbaş, Ahmet Macit; Volkan, Mürvet; Department of Metallurgical and Materials Engineering (2010)
The aim of this study is to produce maghemite nanoparticles by using different production methods. To achieve this purpose Sol-Gel Processing and Microwave Synthesis methods were employed. Suitable characterization techniques like XRD, TEM, BET, and VSM were performed to control the properties of the synthesized particles whether they are suitable for certain applications. In the sol-gel part of the study two different routes were employed to obtain maghemite nanoparticles. In the first route TEOS (tetraeth...
