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 parameter in the range 12.51 - 12.53 angstrom, other phases are identified as icosahedral, Al3Fe and Al-13(Fe,V)(4) by XRD. SEM was used to examine the morphological changes and quantitative element analysis to reveal the chemical composition of these phases in specimens. Various phase morphologies such as starlike, band shape and needlelike intermetallics were observed in these products, whereas the primary phase crystal structure is cubic and stable.

Effect of Cu addition on the microstructural constituents and mechanical properties of twin roll cast AlFeMnSi alloys Meydanoglu, Onur; Birbaşar, Onur; Ulus, Ali; Beyhan, Bariş; Kalay, Yunus Eren (2015-01-01) In this study, the effect of copper addition on microstructural evolution, mechanical and corrosion properties of twin roll cast (TRC) AlFeMnSi alloy system mainly used in container foil applications was investigated. Microstructural characterization studies were conducted on as-cast, homogenization annealed and final products by employing optical and scanning electron microscopes. The mechanical properties of the samples obtained from compositional were determined at the thickness of final product by tensi...
Effect of operating parameters on selective separation of heavy metals from binary mixtures via polymer enhanced ultrafiltration Muslehiddinoglu, J; Uludağ, Yusuf; Ozbelge, HO; Yılmaz, Levent (Elsevier BV, 1998-03-18) Performance of continuous polymer enhanced ultrafiltration (PEUF) method was investigated for removal of mercury and cadmium from binary mixtures. This method includes the addition of polyethyleneimine (PEI) as a water soluble polymer to bind the metals, which was followed by ultrafiltration operation performed on both laboratory and pilot scale systems. The influence of various operating parameters such as temperature, metal/polymer ratio, presence of calcium ions and pH on retention of metals and permeate...
Effects of mold temperature and vacuum in resin transfer molding Akgül, Eralp; Kaynak, Cevdet; Department of Metallurgical and Materials Engineering (2006) The purpose of this study was to investigate the effects of mold temperature, initial resin temperature, and the vacuum, applied at resin exit ports, on the mechanical properties of epoxy matrix woven glasss fiber reinforced composite specimens produced by Resin Transfer Molding (RTM). For this purpose, six different mold temperatures (25º, 40º, 60º, 80º, 100º, and 120ºC), two initial resin temperatures (15º and 28ºC), and vacuum (0.03 bar) and without vacuum (~1 bar) conditions were used. Specimens were ch...
Effects of processing parameters on mechanical and thermal properties of glass mat reinforced nylon 6 composites Akkaoui, W; Bayram, Göknur (SAGE Publications, 2004-01-01) Nylon 6 (PA6)/Glass Mat (GM) composites and pure PA6 were prepared by compression molding technique and the effects of molding temperature, pressure application time and GM content on the final properties of the materials were investigated. At each temperature and pressure application time, the composite with one layer GM had higher tensile strength, tensile modulus but lower % elongation at break than neat PA6. Processing parameters did not significantly influence the tensile behavior of the pure PA6 and P...
Effects of RTM mold temperature and vacuum on the mechanical properties of epoxy/glass fiber composite plates Kaynak, Cevdet; Isitman, Nihat Ali (2008-08-01) The purpose of this study is to investigate the effects of mold temperature, application of vacuum at resin exit ports, and initial resin temperature on the mechanical properties of epoxy matrix woven glass fiber reinforced composite specimens produced by resin transfer molding (RTM). For this purpose, six mold temperatures (25, 40, 60, 80, 100, and 120 degrees C), two initial resin temperatures (15 and 28 degrees C), and vacuum (0.03 bar) and without vacuum (similar to 1 bar) conditions are utilized. Speci...
