FP7 Marie Curie Project from Mert Efe
RESEARCH
Project aims to observe the in-situ formation and evolution of the surface defects during magnesium
sheet forming by means of a novel test mechanism involving high-resolution photography and digital
image correlation (DIC) techniques. As an alternative to conventional macro-scale tests, the
mechanical behavior of materials will be investigated at microstructure scale (grain-scale).
Interactions between microstructure evolution and defect formation will be analyzed, which will
results in solutions for defect minimization and elimination.
TÜBİTAK 1007: Gas Turbine Blades-MILKANAT
Turbine technology used in gas turbine engines is also utilized in automotive, aviation and space
industries. These strategic parts have been imported so far. With this project, however, the turbine technology know-how, infrastructure and development capability will be established in Turkey making it possible to manufacture, do maintenance of, and repair gas turbine blades.
The technology know-how gained in this project, as a result of research and development
carried out at METE under the supervision of Asst. Prof. Dr. Bilge Imer, will pave the way for
further protective coating developments in other so-called strategic industries. This project
started in 2014 with a total budget of 3 million TL allocated to Dr. İmer and METE to carry
out turbine blade coating R&D with CVD technique.

LIGHT & ENVIRONMENTALLY FRIENDLY CAR PROTOTYPE by
Foundry, Metal Processing and Automotive Materials Laboratory
This project is a graduate research project supporting M.S and Pd.D thesis. Onur Demirel performed
his thesis designing an aluminum spaceframe made of aluminum 6061 and Al-Sİ-Mg alloys. Spaceframe was modelled using Ansys static and dynamic finite element analysis code. Tortional stiffnes
of the spaceframe was analyzed under constant amplitude non proportional loading conditions.
RESEARCH
A clay model was produced then 3D files was obtained after a series of surface operations, A class
modeling was completed. Polstyrene ¼ and 1/1
models were produced then a prototype car was
assembled a spaceframe using TIG welding of 6061
extrusions and Al%7SiMg T6 alloy .
COLLABORATION OF INDUSTRY AND ‘METE’
The project was funded by Turkish Ministry of Science Industry and Technology and ERTEX
company, supervised by Prof. Dr. Ali Kalkanlı from Department of Metallurgical and Materials
Engineering Middle East Technical University. The chassis and the space-frame of the diesel
and electric car prototypes were modelled and produced by casting in our department.
Diesel and electric prototypes were completed and tested on the roads.

Collaborations of Turkish Defense Industries
and “METE”
Currently there are several projects that are funded by Turkish Ministry of Science Industry and
Technology, Under secretariat for defense Industries (SSM) and Turkish Defense Industries supervised by Prof. İshak Karakaya from Department of Metallurgical and Materials Engineering of Middle
East Technical University. Some of the projects are:
Development of Electrochemical Processes for Materials of Optomechanical Carrier of Cooled
Infrared Detectors is in progress by colaboration with Aselsan.
Electrochemical Production of Tungsten Refractory Metal Powders and Sintering is in progress by
colaboration with ROKETSAN.
RESEARCH
MEGAP IS THE FIST JOINT VENTURE FROM
‘METE’ IN METU TECHNOPOLIS
MEGAP
The invension of an electrochemical process for production of tungsten powder
in molten salt solutions has led Prof.İshak Karakaya and a former graduate student Metehan Erdoğan (presently Assist.Prof. at Yıldırım Beyazıt University)
from the Department of Metallurgical and Materials Engineering of Middle East
Technical University to establish MEGAP to commercialize the process. The process was patented in Turkey, Russia and Canada. Adaptation of process to industrial practice is in progress.
In addition, MEGAP is taking part in Research and Development projects of commercial and Turkish Defense Industry companies. Its supports to construction
and development of TEMP (Thermochemical and Electrochemical Material ProProf. Ishak Karakaya cessing) laboratories are important contributions to METE.
TÜBİTAK 1003: Electronic Packaging of MEMS
Microelectromechanical systems (MEMS) are micron-size devices that can sense or manipulate the
physical world. MEMS integrates microelectronic circuits and mechanical structures on the same
chip. MEMS devices require good encapsulation in terms of mechanical protection, hermetic sealing and electrical connection. A research team consists of scientists from METE, METU-MEMS and
ASELSAN will be working together in a TUBITAK 1003 project to develop new materials and procedures for electronic packaging to be used in critical MEMS applications, The project is supervised
by Assoc Prof. Y. Eren Kalay.
MEMS are often used in

SEDA’s Exhibition at the Library Hall
Seda Oturak, senior METE student, landed her own exhibit of scanning electron
microscopy micrographs in university library hall. Seda used false coloring technique to display the electron microscopy images in color. The exhibit includes
several examples of electron microscopy studies from nanowires to copper
smelting slags conducted by our graduate students. The exhibit attracted a great
attentions of undergraduate and graduate students, university faculty and staff.

Cavit’s Success in
TUBITAK Competition
AWARDS
Cavit Eyövge, senior METE students, has won the TUBITAK’s Capstone Design Project Competition with his project on metal hydride batteries. Normally metal hydride batteries makes use of AB5 compounds with discharge
capacity of around 380 mAh/g. Cavit Eyövge in his study made an attempt to replace AB5 with Mg based compounds with a potential discharge capacity of three times that of AB5. The study concentrates on methods of
encapsulating Mg based active material so as to prevent its corrosion in alkaline environment. We congratulate
Cavit and his academic advisor Prof. Tayfur Ozturk.
