Ni-based superalloys have gained importance in aerospace and energy industries due to their excellent mechanical properties at elevated temperatures. Conventional manufacturing methods such as casting and forging create defects having adverse effects on the service performance. Moreover, microstructures of cast and wrought products contain brittle phases, which negatively affect the machinability. In recent years, additive manufacturing techniques have been developed for production of Ni-based superalloy components having extremely complex shapes and/or functionally graded layers. This study focusses on optimization of the heat treatment procedure for the IN718 parts additively manufactured by selective laser melting. The relationships between microstructure and mechanical properties will also be investigated.

Frequency Modulated Raman Spectroscopy Greco, Silvio; Dal Zilio, Simone; Bek, Alpan; Lazzarino, Marco; Naumenko, Denys (2018-02-01) The coupling of plasmonic and mechanical properties at the nanoscale is of great potential for the development of next generation devices capable to detect weak forces, mass changes, minute displacements and temperature induced effects. Both the transduction of mechanical motion to the scattered light fields in term of polarization or intensity modulation and plasmon-driven mechanical oscillations have already been demonstrated. Quasi static tunable hot spots have recently been designed and applied to surfa...
Analysis and verification of a pyroshock test system Küçükbayram, Anıl İsmail; Özer, Mehmet Bülent; Department of Mechanical Engineering (2021-2-03) In the aerospace industry, systems, subsystems, and units are exposed toexplosive events during their lifecycle. Any explosive event creates shock in the structure, and it propagates until it is damped. This shock wave may be hazardous for some electronic and optical components. It may damage a component and cause failure in the equipment. For this reason, satellite equipmenthas tobe qualifiedto withstand all static and dynamic loads encountered during launch and operational life. Thus, one of ...
Thermal effects of gate connected field-plates and surface passivation on AlGaN/GaN HEMTs Kara, Doğacan; Okutucu Özyurt, Hanife Tuba; Dönmezer, Nazlı; Department of Mechanical Engineering (2018) AlGaN/GaN high electron mobility transistors (HEMTs) are widely preferred in automotive, space, and military applications due to their superior electrical and thermal properties. However, when operated in full capacity, their electrical reliability drops significantly due to electron collapse, device degradation, concentrated heating, and mechanical stresses. To increase the reliability and maximum performance of GaN HEMTs, field-plate and surface passivation technologies are used frequently. Although signi...
Design Optimization of Variable Stiffness Composite Laminates Using Surrogate Models for Compliance and Buckling Load İnci, Hasan; Kayran, Altan (2017-09-22) Usage of composite materials in aerospace industry has never been so wide in our world. Starting from the development of composites, the analyses were only done for straight fiber composites. With the improved manufacturing capabilities, designers have the ability to design more complex shapes for composites, which allows more efficient structures. In the past two decades, variable stiffness (VS) composite laminates are introduced to the literature. Within these two decades, researchers working on VS concep...
IMPLEMENTATION OF STRONG LIGHT-MATTER INTERACTION FOR FABRICATION AND LIGHT MANAGEMENT OF THIN CRYSTAL SILICON SOLAR CELLS Zolfaghari Borra, Mona; Bek, Alpan; Ünalan, Hüsnü Emrah; Department of Micro and Nanotechnology (2021-7-29) The integration of photonic components with electrical elements on the same silicon chip may lead to the development of new technologies. One limitation is the space available on the wafer surface, which is restricted. Currently, conventional fabrication techniques produce devices only on the top thin layer of the wafer surface. As a result, new architectural designs are required. Producing functional components deep inside Si without creating damage to the surfaces is a potential technique for overcoming t...
