Research-Outreach-Awards - Middle East Technical University
2013-2015 Content Research-Outreach-Awards (2013-2015) Metallurgical and Materials Engineering Mission Statement Undergraduate Program Graduate Program Faculty and Staff Reserch Areas Laboratories and Centers Campus Map and Contact PAGE 4 #1 in ENGINEERING COLLEGE Metallurgical and Materials Engineering Department is ranked first in Faculty of Engineering based on the number of international articles published in reputable scientific journals per faculty member. In 2013, RESEARCH METE we published 56 interna- tional journal articles and were SCI indexed. OUR PROJECTS As of 2013, There are 28 national projects and 1 international project are being conducted with 520.000 TL yearly budget 43 PAGE 5 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. PAGE 6 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. PAGE 7 Dr. Kalay received EU support for “Synchrotron X-ray” based Research Dr. Kalay’s research group received EU support for their X-ray scattering based experiments in Europe’s prestigious synchrotron light facilities. Dr. Kalay’s team (Merve Genc, Can Yildirim, Mustafacan Kutsal and Fatih Sikan) have conducted critical in-situ XRD and WAXS/SAXS experiments to get the insights of the nucleation and phase selection hierarchy during devitrification of metallic glasses under farfrom equilibrium conditions. Merve Genc (Ph.D. Candidate) at Dr. Kalay at ALBA, Barcelona, Spain. RESEARCH Elettra, Trieste, Italy. and the NOBEL Prize goes to…. “Incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps.” NOBEL COMMITTEE The invention of blue LED light in 90s by Isamu Akasaki, Hiroshi Amano and Shuji Nakamura has made revolution in energy, communication, defense, space technology and many other fields, and received 2014 Nobel prize in Physics. This has further strengthened the importance of Materials Science Assist. Prof. Bilge İmer and Engineering. Asst. Prof. Dr. Bilge İmer from METU-Metalurgical and Materials Engineering Department worked with Nobel Laureate Prof. Shuji Nakamura, Prof. Steven DenBaars and Prof. James Speck in her PhD at University of California Santa Barbara (UCSB). Under her doctoral study thesis Improved Quality III-Nitride Films and Devices, Dr. İmer filed two patents that are currently in use by LED companies. SOORA, the company Prof. Nakamura is a partner of, has been conducting R&D on LED and lasers also utilizing these patents. In the upcoming years, it will be possible to find high power non-polar blue and green LEDs in the market that uses Dr.İmers work PAGE 8 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 Thermal Camera Airbag Systems Gyroscopes Microbolometers Schematics of MEMS Bonding made by thermal evaporation PAGE 9 BUREAU VERITAS CERTIFICATE PROGRAM 10 WEEK CERTIFICATE PROGRAM (For 3rd & 4th Grade Students—82 Students) March-June 2014 OUTREACH PERFORMANCE MONITORING AND CONTROLLING IN ADMINISTRATIVE SYSTEMS RISK MANAGEMENT QUALITY PLANNING AND PRODUCT APPROVAL PROCESS MEASUREMENT SYSTEM ANALYSIS, CAPABILITY ANALYSIS SUPERVISION, CERTIFICATION, TESTING SERVICE AND AGREEMENTS SSAB SWEDISH STEEL SEMINAR SERIES Björn Helgesen, Tomas Visur, Carl Chapman «SSAB is a global leader in high strength steel.» April 16th , 2014 For 3rd & 4th Grade Students—92 Students Production and Metallurgy Steels on Heavy Transport, Lifting, Automotive Welding of High Strength Steel Design Principles Fatigue Forming PAGE 10 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.
