In the present study, a new type of Ti-Mg/AZ91 composite has been successfully manufactured using pressureless infiltration method to be used for structural and functional applications. Porous Ti6Al4V alloy skeleton structure was produced by loose powder sintering which was then filled with either liquid magnesium or AZ91 alloy at around 800 qC under high purity argon atmosphere in order to obtain Ti-Mg composites. Starting porous preforms contained 40 vol% open porosity, and nearly all of the pores were completely filled with Mg or Mg alloy after infiltration without formation of secondary phases and intermetallics. Quasi-static compression tests along with hydrogen evolution tests were performed in simulated body fluid environment in order to understand the corrosion tendency of the Ti-Mg composites and to evaluate their potential applications in biomedical industry

As a promising approach in tissue engineering, decellularization has become one of the mostly-studied research areas in tissue engineering thanks to its potential to bring about several advantages over synthetic materials since it can provide a 3-dimensional ECM structure with matching biomechanical properties of the target tissue. Amniotic membranes are the tissues that nurture the embryos during labor. Similarly, these materials have also been proposed for tissue regeneration in several applications. The ...
Processing and characterization of high density tungsten-nickel-iron alloys
Çalışkan, Necmettin Kaan; Bor, Şakir; Durlu, Nuri; Department of Metallurgical and Materials Engineering (2013)
In the present study, processing of W-Ni-Fe alloys by liquid phase sintering technique has been investigated. Effect of sintering atmospheres (hydrogen and vacuum), tungsten content altering from 90 to 97 wt.%, Ni/Fe ratio varied from 2 to 4 and post sintering treatments (heat treatment and swaging) on the microstructure and mechanical properties of W-Ni-Fe alloys have been analyzed. Liquid phase sintered alloys were characterized by mechanical tests, electron microscopy and XRD studies, thermal analyses an...

Soheila, Zenaili; Çetin, Barbaros; Özer, Mehmet Bülent; Süleyman, Büyükkoçak (2014-07-03)
In this study, the fabrication of microfluidic devices for dielectrophoretic and acoustophoretic based applications with high-precision CNC machining has been presented. For both devices, molds out of stainless steel have been fabricated, and polymer molding is implemented. For dielectrophoretic device, the metal electrodes have been fabricated using high-precision machining and embedded into the device during the molding process. For acoustophoretic device, piezoelectric slides have been embedded into the ...
Formation and Characterization of Sub-Micron Inert Particle Embedded Nickel Composite Coatings
Yılmaz Tüzün, Özgül; Karakaya, İshak (2017-06-01)
Composite coatings have a wide range of application areas requiring improved mechanical and tribological properties. Due to its enhanced properties, Ni-Al2O3 electro-co-deposition rather than pure Ni electrodeposition was investigated. A typical sulfamate bath was used to evaluate the effects of current density on hardness and the amount of deposited Al2O3. It was found that increase in current density increases the hardness and deposited wt.% Al2O3 particles within the parameter ranges covered in this stud...
Synthesis of silver nanowires through polyol process
Coşkun, Şahin; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2012)
Nanotechnology enabled synthesis of various shapes and morphologies of conventional materials. Nanotubes, nanoparticles, quantum dots and nanowires are the new form of materials. Especially nanowires have gotten great attention due to their unique physical, chemical and optical properties. Superior properties of nanowires are based on their high surface area and two quantum confinement directions. Silver is one of the most conductive metals and it has the highest thermal conductivity. Due to excellent prope...
