In this study, wear behavior of various tools in milling process of Al-4Cu/B4Cp composites was investigated. For this purpose, composite samples were produced by liquid phase sintering to be used in milling operation. Five different cutting speeds at a constant feed rate of 0.20 mm/z were used in order to determine the effect of cutting speed on tool wear and tool wear mechanism in milling of these composites. Milling operations were continued until flank wear limit (V-B)=0.3 mm was attained for each tool. Flank wear was determined by using optical microscopy whereas wear mechanisms were examined by using scanning electron microscopy (SEM). Experimental results brought out that triple coated tool showed the highest wear resistance at all cutting speeds. In addition lower cutting speeds yielded lower tool wear for all tools.

Effect of solidification rate on spatial distribution of SiC particles in A356 alloy composites CETIN, Arda; Kalkanlı, Ali (Elsevier BV, 2008-08-26) The damage and deformation behaviour of particulate reinforced metal matrix composites (PMMCs) can be highly sensitive to local variations in spatial distribution of reinforcement particles, which markedly depend on melt processing and solidification stages during production of PMMCs. The present paper attempts to study the effect of solidification rate on cluster formation in an Al-Si-Mg (A356) alloy composite reinforced with SiC particles and to explore the applicability of spatial functions to PMMC micro...
Effect of spraying rate on microstructure of spray deposited Al-Fe-V-Si alloy Kalkanlı, Ali (Informa UK Limited, 2003-12-01) In this study gas atomisation and spray deposition of a series of AlFeVSi alloys were carried out. Traces of transient liquid were observed as lamellar structure in the middle of the specimen. The heat transfer conditions of this structure were modelled by finite difference calculation. Metallographic specimens for optical microscopy were prepared from the preforms formed in these processes. Optical microscopy showed the presence of dispersoids in the specimens. The dispersoids were characterised as AlFeVSi...
Effect of Feed Rate on Tool Wear in Milling of Al-4% Cu/B(4)C(p) Composite Ubeyli, Mustafa; ACIR, Adem; Karakas, M. Serdar; Ögel, Bilgehan (Informa UK Limited, 2008-01-01) The effect of feed rate on tool wear in milling of B(4)C(p) reinforced aluminum metal matrix composites (MMCs), produced by liquid phase sintering method, was investigated. Milling experiments on these composites were conducted with three different types of cementide carbide tools (uncoated, double coated (TiN+TiAlN) and triple coated (TiCN+Al(2)O(3)+TiN)) for three different feed rates of 0.15mm/z, 0.20mm/z, and 0.25mm/z. After milling experiments, an optical microscope was used to measure the magnitude of...
Effect of gap distance on the mechanical properties and cross-sectional characteristics of the MIG-MAG butt wells Kaşıkçı, İlker; Ankara, Osman Alpay; Department of Metallurgical and Materials Engineering (2003) This study was undertaken with the objective of determining the effect of gap distance on the weld bead geometry and the mechanical properties of the weldments. Low-alloyed and low carbon steel plates were welded under different conditions where each weldment had different gap distance and weld bead grooves. The influences of welding parameters namely, welding speed, current and voltage on the weld bead were examined in terms of weld bead penetration and heat affected zone and weld metal zone hardness varia...
Control of the thickness distribution of evaporated functional electroceramic NTC thermistor thin films Schmidt, R.; Parlak, Mehmet; Brinkman, Am (Elsevier BV, 2008-04-01) In this work the thickness distribution of NTC thermistor thin films produced by low deposition rate (0.8 nm s(-1)) electron-beam evaporation is investigated. The target preparation, deposition conditions and geometrical set-up of the evaporation mechanism are described in detail. The evaporation geometry is shown to be critical for the thickness distribution of evaporated films. The film thickness distribution of evaporated layers was measured across a macroscopic film surface using Alpha Step stylus profi...
