Recently, there has been a great attention on HEAs to obtain robust mechanical, magnetic and thermal properties. However, there are limited studies on low density high entropy alloys (LDHEA) due to difficulty to produce such alloys with single or dual solid solution phases from low density elements. The development of LDHEA particularly for industrial applications is one of the challenge in this field. In the present study, HEA ability of low density elements are studied in details. In this manner, light weight elements such as Al, Si, Ti, V, Mn were studied using empirical thermo-physical parameters to test their ability to be produced as HEA. The candidate AlTiVMnSi X (x=0.25, 0.50) LDHEAs were produced using arc-melting and induction melting techniques. Single phase LDHEAs and small amount of intermetallic compounds (ICs) with densities as low as 4.61 gr/cm 3 , 730 and 821 HV were produced. We discussed mechanisms of the LDHEA production and the critical properties through a combined study of mechanical and microstructure analyses. This project is being supported by TUBITAK, under the project number 216M058.

Design of oxygen-doped TiZrHfNbTa refractory high entropy alloys with enhanced strength and ductility Iroc, L.K.; Tukac, O.U.; Tanrisevdi, B.B.; El-Atwani, O.; Tunes, M.A.; Kalay, Yunus Eren; Aydoğan Güngör, Eda (2022-11-01) © 2022Refractory high entropy alloys (RHEAs) are considered promising materials for high-temperature applications due to their thermal stability and high-temperature mechanical properties. However, most RHEAs have high density (>10 g/cm3) and exhibit limited ductility at low temperatures and softening at high temperatures. In this study, we show that oxygen-doping can be used as a new alloy design strategy for tailoring the mechanical behavior of the TiZrHfNbTa alloy: a novel low-density (7.98 g/cm3) ductil...
Preparation and characterization of magnetic nanoparticles Küçük, Burcu; Volkan, Mürvet; Department of Chemistry (2009) Magnetite (Fe3O4) and Maghemite (γ-Fe2O3) are well-known iron oxide phases among magnetic nanoparticles due to their magnetic properties, chemical stability, and nontoxicity. They have gained acceptance in several fields of application of nanomaterials such as magnetic recording systems, magnetic refrigeration, magneto-optical devices, magnetic resonance imaging, magnetic separation techniques and separation and purification of biological molecules. Recently, there is a growing interest in the synthesis of ...
Design and manufacturing of electrically conductive composites via microvascular channels Tanabi, Hamed; Güvenç Yazıcıoğlu, Almıla; Department of Mechanical Engineering (2017) Owing to their tunable properties and wide range of applications, conductive composites are one of the most important, interesting, and active areas in advanced composite research. For instance, among numerous types of health-monitoring and damage-sensing sensors that can be integrated into composites, electrically conducting sensors offer a simple, cost-effective, and durable option for structural health monitoring in fiber reinforced composites. Despite these advantages, the development of internal electr...
Development of high strength aluminum matrix composite backing plates for ballistic armor Durmaz, Tayfun; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2017) Recently, aluminum and aluminum alloys have gained great importance in engineering applications by the help of technological developments. Today, it is possible to see aluminum alloys in very different sectors of industry because of their superior properties. Some of these important properties are high specific strength, lightness and ductility. In addition, it has low density, high corrosion resistance and high mechanical properties that make aluminum crucial in transportation, construction, packaging, hou...
Design and characteristics of high performance mid-wavelength type-2 superlattice sensors Oğuz, Fikri; Bek, Alpan; Arslan, Yetkin; Department of Micro and Nanotechnology (2018) Type-II Superlattices (T2SLs) are bandgap engineered structures that have attracted a lot of attention in the last couple of decades and is still some of the hot topics in infrared imaging applications. T2SLs are the most promising member of the quantum structured infrared family. By the end of maturity period of T2SLs, Focal Plane Array (FPA) level products have been released since a decade. Offering performance compatible with high-end infrared systems, yielding respectable results and still being open to...
