The aim of this study is to investigate the effect of building direction on mechanical properties of the parts fabricated using Ti6Al4V alloy powders by electron beam melting method. Three specimens in three different directions (X, Y and Z) were produced and to see the effect of surface roughness on mechanical properties, one of the samples in each direction were machined by lathe. The results of tension tests on samples produced in three directions according to ASTM E8 standard revealed that yield and tensile strength of the samples built in Z direction are higher than the related properties of the samples built in X and Y directions. Yield and tensile strength of the samples built in each of the direction comes out to be higher than the same properties of the wrought or cast Ti6Al4V parts. Specimens displayed a mixed ductile-brittle fracture characteristic and the microstructure is mainly Widmanstatten / basket weave and α lamellar microstructure was observed inside the prior β grains.

Computational modelling of electro-active polymers
Dal, Sinan Fırat; Göktepe, Serdar; Department of Civil Engineering (2019)
This study is concerned with the stability of Electro-Active Polymers (EAPs) having geometries with periodic microstructures subjected to coupled electromechanical effects. For this purpose, coupled electromechanical equations, which are nonlinear, are discretized using the Finite Element Method (FEM) under the prescribed boundary conditions. EAPs are smart materials that may undergo large mechanical deformations when subjected to an electric field. Unlike many other materials that show permanent deformatio...

Investigations on bulk glass forming ability of titanium based multicomponent alloys
Süer, Sıla; Mekhrabov, Amdulla O.; Department of Metallurgical and Materials Engineering (2008)
The aim of this study is to investigate the bulk glass forming ability (BGFA) of Ti-based alloy systems. These investigations were carried out in two main parts that are complementary to each other: theoretical and experimental. For theoretical studies, which are based on electronic theory of alloys in pseudopotential approximation, Ti-Zr, Ti-Co and Ti-Cu alloys were chosen as the binary systems. Alloying element additions were performed to each binary for the investigation of the BGFA of multicomponent Ti-...
Structural and mechanical investigations of magnesium and fluoride doped nano calcium phosphates
Sun, Zehra Pınar; Evis, Zafer; Department of Micro and Nanotechnology (2009)
The aim of this study was to investigate the microstructure and mechanical properties of pure and Mg2+ and F- doped nano-calcium phosphate (CaP) powders, which were synthesized by precipitation method. After the drying and calcination processes, the samples were sintered at 1100ºC for 1 hour. High densities were achieved except for the 7.5 % mole Mg doped samples. Microstructure of the CaPs were investigated by X- ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Mi...
Solidification and crystallization behaviour of bulk glass forming alloys
Aybar, Sultan; Akdeniz, Mahmut Vedat; Department of Metallurgical and Materials Engineering (2007)
The aim of the study was to investigate the crystallization kinetics and solidification behaviour of Fe60Co8Mo5Zr10W2B15 bulk glass forming alloy. The solidification behaviour in near-equilibrium and non-equilibrium cooling conditions was studied. The eutectic and peritectic reactions were found to exist in the solidification sequence of the alloy. The bulk metallic glass formation was achieved by using two methods: quenching from the liquid state and quenching from the semi-state. Scanning electron microsc...
