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 flank wear on the tools. Flank wear limit value, (V(B))=0.3mm was selected as a reference value for comparison of these tools. On the other hand, tool wear mechanisms were examined with the help of a scanning electron microscope (SEM). Experimental results indicated that higher feed rates led to lower tool wear for all type of tools and coated tools exhibited better performance than uncoated tool with respect to the flank wear.

Effect of microstructural modification on damage tolerance of 34CrMo4 shaft steel
Ozcan, Burak; Gurer, Goksu; Gür, Cemil Hakan (Wiley, 2020-06-01)
Overall damage tolerances of the heat-treated 34CrMo4 steels having ferritic-pearlitic, bainitic, and tempered-martensitic microstructures were evaluated based on their threshold stress intensity factor prior to small crack propagation, fatigue strength, and fracture toughness under static loading. Kitagawa-Takahashi diagrams were constructed to determine the limiting size of small crack propagation. The micromechanical effects of carbide morphology and phase distribution on quasi-static and dynamic mechani...
Effect of stress ratio on the rate of growth of fatigue cracks in 1100 Al-alloy
Bilir, Ömer.G.; Harun, Metin (Elsevier BV, 1990-1)
Axial load fatigue crack propagation tests were conducted on notched sheet specimens made of 1100 aluminum alloy. These tests were made at stress ratios (ratio of the minimum stress to the maximum stress) ranging from −0.5 to 0.5 in order to study the effects of stress ratio on fatigue crack growth. Experimental fatigue crack propagation data were analysed using Paris-Erdoǧan stress intensity analysis. The data from the tests at different stress ratios showed that two regions, namely, region I and region I...
Effect of tube spinning and subsequent heat treatments on strength, microstructure and residual stress state of AISI/SAE type 4140 steel
Gür, Cemil Hakan (Informa UK Limited, 2003-11-01)
In the present study, the effects of deformation percentage (23, 30, 50 and 66%) and subsequent stress relief and tempering heat treatments on the mechanical properties, residual stress state and microstructure of AISI/SAE type 4140 steel tubes manufactured by forward spinning were evaluated. Mechanical properties were determined by means of hardness and tensile tests. The tangential component of the surface residual stresses was determined by a slitting method. Plastic deformation of the metal during spinn...
Effect of initial powder morphology on thermal and mechanical properties of stand-alone plasma-sprayed 7 wt.% Y2O3-ZrO2 coatings
Ercan, Batur; Trice, Rodney W.; Wang, Hsin; Porter, Wally (Elsevier BV, 2006-11-05)
The effects of starting powder morphology on the thermal and mechanical properties of stand-alone plasma-sprayed 7 wt.% Y2O3-ZrO2 (YSZ) coatings were studied. Two powder morphologies were investigated: an agglomerated and sintered powder (referred to presently as "AS") and a powder manufactured using plasma spheroidization to create hollow spheres (referred to presently as "HS"). Coatings made from AS powders contained 0.21 wt.% SiO2 impurity, twice as much as observed in coatings made from HS powders. Prop...
Effect of cutting speed on tool performance in milling of B4Cp reinforced aluminum metal matrix composites
Karakas, M. Serdar; Acir, Adem; Ubeyli, Mustafa; Ögel, Bilgehan (Elsevier BV, 2006-09-14)
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. ...
