This study has focused on the influence of size and content of SiC particle incorporation on the wetting behavior of the Ticusil brazing filler alloy and on its brazing performance in C/SiC composite/Ti6Al4V alloy joints. The effect of the size and content of additive SiC particles on the variation of molten brazing filler alloy contact angle was recorded at various brazing time and temperatures. Moreover, the microstructural evolution and mechanical properties of the additive containing C/SiC composite/Ti6Al4V alloy joints produced by the brazing method were investigated. The contact angles in both brazing filler alloys containing nano- and micro-sized SiC particles exhibited a sudden decrease with time during isothermal holding as observed in as-received brazing filler alloys. As the quantity of the SiC particles increased in the brazing alloy, the recorded contact angle values including the final, stable contact angle increased, while the time for the drastic contact angle change also increased remarkably. Compared to as-received counterparts, the addition of 2 wt.% nano-sized SiC and 1 wt.% micro-sized SiC particles improved the shear strength of the joints by 35 and 8%, respectively. Although the recorded contact angle values were close to each other in brazing alloys containing SiC particles with different sizes (37 and 42 degrees for 1 wt.% micro-sized and 2 wt.% nano-sized additions), higher increment was achieved in the mechanical performance of the joints with nano-sized SiC additive due to more homogeneous reinforcement effect of the nanoparticles. The results indicated that the optimum brazing filler alloy contact angle for the highest shear strength is similar to 40 degrees for both nano- and micron-sized additive containing Ticusil filler alloy.

A Molecular Dynamics Study on the Local Structure of Al90Sm10 Marginal Metallic Glass and Liquid Sarıtürk, Doğuhan; Kalay, Yunus Eren (2023-01-01) The liquid and the amorphous Al90Sm10 marginal metallic glassy alloy are investigated using Molecular Dynamics. The Al90Sm10 system consisting of 32,000 atoms is simulated under the constant number of atoms, pressure, and temperature (NPT) ensemble where the temperature and pressure are controlled via Nose–Hoover thermostat and barostat, respectively. The corresponding liquid model is initially held at 2300 K; then, the liquid is continuously cooled down to 300 K with a constant cooling rate of 1010 Ks−1, d...
Interfacial reaction kinetics and microstructural evolution of C/SiC composites to metal joints Saltık, Simge; Dericioğlu, Arcan Fehmi; Department of Metallurgical and Materials Engineering (2021-9-09) In the present study, joining of two dissimilar materials namely C/SiC composites and Ti6Al4V alloys by brazing using Ag-Cu based brazing filler alloys have been investigated. The effect of active Ti element content, additive particle size/amount in the filler alloy together with the reinforcement structure, material properties of the C/SiC composite on the interface evolution mechanism and resulting mechanical performance of the brazed joints have been examined. Additionally, apart from the brazing studies...
A density functional theory study of oxidation of benzene to phenol by N2O on Fe- and Co-ZSM-5 clusters Fellah, Mehmet Ferdi; Önal, Işık (2009-06-01) Density functional theory (DFT) calculations were carried out in the study of oxidation of benzene to phenol by N2O on relaxed [(SiH3)(4)AlO4M] (where M=Fe, Co) cluster models representing Fe- and Co-ZSM-5 surfaces. The catalytic cycle steps are completed for both Fe-ZSM-5 and Co-ZSM-5 clusters. The general trend of the results that were obtained in terms of activation barriers for the Fe-ZSM-5 cluster is in agreement with the experimental and theoretical literature. It was observed that the phenol formatio...
Synthesis and characterization of aluminum alloy 7075 reinforced with silicon carbide particulates Kalkanlı, Ali (2008-01-01) In this study 7075 matrix alloy is chosen and SiC particles having average particle size of 29 mu m was incorporated into the alloy at the liquid state before vertical pressure casting. Four different additions of SiCp were made and the weight fractions used are 10%, 15%, 20% and 30%. Composites were processed by vertical pressure/squeeze casting machine developed at Middle East Technical University (METU) under 80 MPa pressure. The mold is specially designed to produce specimens for tensile and three point...
INVESTIGATION OF THE MICROSTRUCTURAL AND MECHANICAL PROPERTIES OF DP500 AND DP700 QUALITY STEELS WELDED WITH DIFFERENT HEAT INPUTS Yılmaz, Kardelen; Ögel, Bilgehan; Batıgün, Caner; Department of Metallurgical and Materials Engineering (2023-1-25) In this study, effect of different heat input values from different welding techniques on microstructural and mechanical properties of Dual Phase (DP) steel DP500 and DP700 are evaluated. The welding operations were carried out manually by using Tungsten Inert Gas Welding (TIG), Metal Active Gas (MAG) Pulse Arc Welding and MAG Cold Metal Transfer (CMT) arc methods with keeping different heat inputs. The specimens were welded under specified conditions. They were initially evaluated by metallographic methods...
