The Site and Phase Preferences of Mo Element in a Model Ni-Al-Mo Superalloy

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 matrix. Depending on the siteand phase preferences of alloying elements, novel types of these materials can be developed. The current study aims to revealsite and phase preferences of X = Mo element via first-principles calculations and energy-dispersive X-ray spectroscopy(EDS) technique. To conclude, X = Mo atoms prefer to occupy Al sites of γ' precipitates and participate into γ matrix.


The effect of peripheral circuits on the total pi-electron energies of cyclacenes
Türker, Burhan Lemi (2000-01-01)
Within the framework of the Huckel molecular orbital theory, certain linear models are developed to express the contribution of peripheral circuits of cyclacenes into their total pi -electron energies, which explain why cyclacenes exhibit the cryptoannulenic behavior as their peripheral circuits which are annulenic in character.
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 Ni, Al, and X atoms. Therefore, in the current work, the site occupancy tendencies of transition X metals were revealed via first-principles ab initio calculations at 0 K. Bonding features of Ni-Al, Ni-X, and Al-X pairs were simulated by using the charge density difference (CDD), electron l...
The effect of substitutional impurities on the evolution of FeAl diffusion layer
Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (Elsevier BV, 1998-2-13)
The formation and growth characteristics of Fe based aluminide diffusion layers at the Fe-Al interface have been analysed in terms of interfacial interaction potentials based on the statistico-thermodynamical theory of multicomponent alloys combined with electronic theory in the pseudopotential approximation. The pairwise interatomic interaction potentials and partial ordering energies have been calculated to predict the effect of various alloying additions on the activity coefficient of Al atoms in α-Fe0.9...
The electronic structure of GanPm(n+m = 5, 17, 29, 35), Ga13P4 (in SiO2) and Ga13P4 (in sodalite) clusters
Katırcıoğlu, Şenay (Elsevier BV, 2004-12-31)
The electronic structure of optimized GanPm(n+m=5, 17, 29, 35) isomers and Ga13P4 cluster in SiO2 matrix and sodalite cage has been studied by Hartree-Fock theory to find out the effect of cluster size and Ga-O bonds on the optical energy gap between LUMO and HOMO. It was found that the optical energy gap of Gal? clusters can be regulated by both the cluster size and the Ga-O interface satisfied by either SiO2 matrix or sodalite cage. The energy gap between LUMO and HOMO of Ga13P4 (in sodalite) cluster has ...
The effect of diabetes on rat skeletal muscle tissues at molecular level
Bozkurt, Özlem; Severcan, Feride; Department of Biology (2006)
In the present study Fourier Transform Infrared Spectroscopy was used to examine the effects of streptozotocin-induced diabetes mellitus on the structural components of slow- and fast-twitch rat skeletal muscles, at molecular level. Diabetes mellitus is a chronic disorder of carbohydrate, fat and protein metabolism, which is characterized by hyperglycemia caused by a defective or deficient insulin secretory response. The effect of diabetes is seen on a variety of tissues leading to important secondary compl...
