The sintering behaviour of tungsten carbide compacts with a eutectic Fe-TiB2 mixture was studied. In order to have a clear view of the mechanisms that occur during liquid phase sintering, the hardness, transverse rupture strength, toughness, and densification values were measured and the micrographs were examined for WC-Fe-TiB2 cermets with varying compositions, sintering times and sintering temperatures. The findings were then with the propeerties known for WC-Fe and WC-Co cermets.

Effect of expandable graphite on flame retardant, thermal and mechanical properties of thermoplastic polyurethane composites filled with huntite&hydromagnesite mineral
Guler, Turkan; Tayfun, Umit; Bayramlı, Erdal; DOĞAN, Mehmet (2017-01-10)
The effect of expandable graphite (EG) was studied on the flame retardant, thermal and mechanical properties of thermoplastic polyurethane (TPU) containing huntite&hydromagnesite (HH). According to the flammability tests results, the synergistic interaction was observed between HH and EG. The maximum limiting oxygen index (LOI value was observed at a ratio of 1:1 (HH:EG) and the highest vertical burning test (UL-94) rating of V0 was observed at a ratios of 4:1, 3:2 and 1:1. The synergistic interaction betwe...
Effect of surface treatment on electrical conductivity of carbon black filled conductive polymer composites
Koysuren, Ozcan; Yesil, Sertan; Bayram, Göknur (Wiley, 2007-06-05)
Two different types of surface modifiers, 3-aminopropyltriethoxysilane and formamide, were applied to carbon black (CB) particles to lower electrical resistivity of polymer composites prepared by treated CB. Two different matrices, low-density polyethylene and nylon 6, were chosen to compound with surface modified CB. Surface energy of CB was increased by adding amine or amide functional groups during surface treatment of CB. According to electron spectroscopy for chemical analysis (ESCA), chemical modifica...
Effect of YF3 on hot-pressed hydroxyapatite and monoclinic zirconia composites
Evis, Zafer (2007-09-15)
Monoclinic zirconia and hydroxyapatite (HA) composites with or without 5 wt% YF3 were synthesized to investigate their mechanical properties and phase stability. HA decomposed to tri-calcium-phosphate and CaZrO3 in the 25 wt% ZrO2-75 wt% HA composite. However, thermal stability of the phases, densification, hardness and fracture toughness were improved when 5 wt% YF3 was added into the system. Five weight percent YF3 increased the transformation of monoclinic-ZrO2 into tetragonal/cubic-ZrO2 by incorporating...
Kinetic investigation of chemical vapor deposition of B4C on tungsten substrate
Karaman, Mustafa; Sezgi, Naime Aslı; Doğu, Timur; Ozbelge, H. Onder (2006-12-01)
Production of beta-rhombohedral boron carbide (B4C) on a tungsten substrate by the chemical vapor deposition from a BCl3-H-2-CH4 gas mixture was achieved. An impinging-jet reactor was used to minimize the mass-transfer limitations on the reaction kinetics, which made a detailed kinetic investigation possible. Results of the XRD and XPS analyses showed that the solid product formed on the substrate is a rhombohedral B4C phase. Both dichloroborane and boron carbide formation rates were found to increase with ...
Effects of granulated blast furnace slag trass and limestone fineness on the properties of blended cements
Delibaş, Tuğhan; Yaman, İsmail Özgür; Hoşten, Çetin; Department of Cement Engineering (2012)
The aim of this research was to determine the effects of the fineness of different mineral additives on loss on ignition, heat of hydration, physical, mechanical and chemical properties of blended cements. For that purpose, portland cement clinker was replaced with granulated blast furnace slag (GBFS), natural pozzolan (NP) and limestone (L) at 6%, 20% and 35% replacement levels. Blended cements containing GBFS and NP were ground to a fineness of 3000, 5000 and 6000 cm2/g. Cements containing L were ground t...
