Size dependent stability and surface energy of amorphous FePt nanoalloy
Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (Elsevier BV, 2019-06-05)
The effects of particle size (2-6 nm) and temperature (300-2700 K) on the stability and local structural evolutions of amorphous equiatomic FePt bulk/nanoalloys have been investigated by combining Embedded Atom Model (EAM)...
Atomic size effect of alloying elements on the formation, evolution and strengthening of gamma'-Ni3Al precipitates in Ni-based superalloys
Eriş, Rasim; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (2019-06-01)
Mechanical properties of Ni-based superalloys strongly depend on phase and site preferences of alloying elements which influence bonding strength within gamma'-Ni3Al precipitates and microstructural characteristics of thes...
DESIGN AND DEVELOPMENT OF HEUSLER ALLOYS FOR MAGNETIC REFRIGERATION APPLICATIONS
Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (2019-01-01)
Cooling systems are used in houses, cars, hospitals, defence systems and many other such areas. However, the gases (chlorofluorocarbons and hydrochlorofluorocarbons) present in today's refrigerant systems are harmful to th...

Yildirim, Mehmet; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (2018-10-01)
The effects of Mo addition on microstructures, phase relationships, order-disorder phase-transition temperatures and room-temperature mechanical properties of Fe50Al50-nMon alloys (n=1, 3, 5, 7, and 9, mole fraction, %) we...
High-temperature site preference and atomic short-range ordering characteristics of ternary alloying elements in gamma '-Ni3Al intermetallics
Eriş, Rasim; Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (Informa UK Limited, 2017-01-01)
Remarkable high-temperature mechanical properties of nickel-based superalloys are correlated with the arrangement of ternary alloying elements in L1(2)-type-ordered. gamma '-Ni3Al intermetallics. In the current study, ther...
Synthesis of AlNiCo core/shell nanopowders
Genc, A. M.; Akdeniz, Mahmut Vedat; Öztürk, Tayfur; Kalay, Yunus Eren (2016-11-01)
Magnetic core/shell nanostructures have been recently received much interest owing to their utmost potential in permanent magnetic applications. In the present work, AlNiCo permanent magnet powders were synthesized by ball...
Microstructural evolution and room-temperature mechanical properties of as-cast and heat-treated Fe50Al50-nNbn alloys (n=1, 3, 5, 7, and 9 at%)
Yıldırım, Mehmet; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (2016-05-10)
The microstructural evolution and room-temperature mechanical properties of Fe50Al50-nNbn alloys (n=1, 3, 5, 7, and 9 at%) were investigated after solidification and subsequent heat treatment. For all the compositions, the...
Microstructural Investigation and Phase Relationships of Fe-Al-Hf Alloys
