The effects of particle size and temperature on the stability and local structural evolutions of amorphous bulk and nanoparticles of the FeNi3 alloys Mehrabov, Amdulla; Irmak, Ece; Akdeniz, Mahmut Vedat (2023-05-01) Abstract: The effects of particle size (2-6 nm) and temperature (300-1900 K) on the stability and local structural evolutions of amorphous bulk and nanoparticles of the FeNi3 alloys have been studied by using classical mol...
Unveiling the effect of Hf-(Mo,W) addition on the coarsening, agglomeration, and dissolution behaviour of γ'-Ni3Al precipitates in model Ni-based superalloys Eriş, Rasim; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (2023-03-05) In compositional design of Ni-based superalloys, atomic size of alloying elements appears as the primary factor affecting alloy strengthening. Depending on atomic size, the phase partitioning preferences of alloying elemen...
On the Optimization of the Microstructural and Mechanical Properties of Model Ni-Based Superalloys Through the Alloying Effects of Refractory Mo and W Elements Eriş, Rasim; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (2022-05-01) In the design and development of next-generation Ni-based superalloys, the addition of refractory impurity elements not only induces better degree of bonding strengthening, but also helps in maintaining structural stabilit...
Effect of Y Addition on the Structural Properties and Oxidation Behavior of Fe60Al40-nYn Alloys (n=1, 3, and 5 at.%) Yildirim, Mehmet; Atas, Mehmet Sahin; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (2022-04-01) The influence of Y addition on the microstructural features, phase relationships, hardness, magnetic behaviour and cyclic oxidation performance of Fe60Al40-nYn alloys (n = 1, 3, and 5 at.%) has been examined in detail. Al8...
Radiation effect studies on partially crystalline bulk amorphous Fe-based metallic glass Kiceci, Pelin Uslu; Akdeniz, Mahmut Vedat; Demirköz, Melahat Bilge; Mehrabov, Amdulla (2022-02-01) The selection of appropriate materials for radiation environments is critical due to the harsh and aggressive conditions found in such environments, which are liable to degrade material properties. Therefore, durability of...
Modeling and Simulation of Structure-Property Relations in Fe-based Nanoalloys via Computational Materials Science Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (2022-01-15)
The Site and Phase Preferences of Mo Element in a Model Ni-Al-Mo Superalloy Eriş, Rasim; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (2021-06-12) It is well accepted that the superior mechanical properties of Ni-based superalloys can be further enhanced by alloying elementaddition which leads to formation of coherently distributed γ'-Ni3Al precipitates within γ-Ni m...
Microstructure, phase relationships and microhardness of Fe60Al40-nHfn alloys (n=1, 3, and 5 at.%) Yildirim, Mehmet; Cetinbakis, Nese; Culu, Ayse; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (2021-04-01) The microstructural evolution, solidification behavior, phase relationships, microhardness and room temperature magnetic properties of the hypoeutectic Fe60Al40-nHfn (n = 1, 3, and 5 at.%) compositions are investigated in ...
The Site Preferences of Transition Elements and Their Synergistic Effects on the Bonding Strengthening and Structural Stability of gamma '-Ni3Al Precipitates in Ni-Based Superalloys: A First-Principles Investigation Eriş, Rasim; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (2021-04-01) Advanced mechanical properties of Ni-based superalloys strongly depend on the site preferences of alloying X elements in gamma '-Ni3Al-X precipitates, which are associated with the partial bonding characteristics between N...
Microstructural Evolution of γ'-Ni3Al Precipitates Affecting Mechanical Properties of Nickel- based Superalloys Eriş, Rasim; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (2020-02-27) Nickel-based superalloys are exceptional materials due to their novel two phase (γ-γ') microstructures. In this study, the effects of ternary alloying X element additions and heat treatment procedures on the microstructura...
