Deformation induced martensite characteristics in Fe-29Ni-2Mn alloy
(Taylor & Francis Ltd, 2008)
Deformation induced martensite characteristics in the austenite phase of Fe-29Ni-2Mn alloy were studied for different austenite grain sizes of alloy. Scanning electron microscopy, transmission electron microscopy, Mossbauer ...
The HN method for half-space Albedo and constant source problems for isotropic and anisotropic scattering kernels
(Pergamon-Elsevier Science Ltd, 2007)
The H-N method, which is developed recently, is used to solve the half-space albedo and the half-space constant source problems for both isotropic and extremely anisotropic scattering kernels. It has been shown that the ...
Effects of substrate temperature and post-deposition anneal on properties of evaporated cadmium telluride films
(Elsevier Science Sa, 2007)
The effects of substrate temperature and post-deposition heat treatment steps on the morphology, structural, optical and electrical properties of thin film CdTe layers grown by vacuum evaporation were investigated. Scanning ...
A New Comparison of Empirical and Semi-empirical Formulae for the (n, 3He) Reaction Cross-sections at 14–15 MeV
(Springer, 2008)
New empirical and semi-empirical formulae have been suggested for the (n, He-3) reaction cross-sections with dependent on asymmetry parameter, S = (N - Z)/A. The (n, He-3) reaction cross-sections at the energy of 14-15 MeV ...
Calculation of 14-15 MeV (n, d) reaction cross sections using newly evaluated empirical and semi-empirical systematics
(Springer, 2008)
In this study, we have investigated the asymmetry term effect for the (n, d) reaction cross sections at 14-15 neutron incident energy. It has been discussed the odd-even effect and the pairing effect considering binding ...
Equilibrium and pre-equilibrium calculations of neutron production in medium-heavy targets irradiated by protons up to 100 MeV
(Pergamon-Elsevier Science Ltd, 2008)
In this study, by using equilibrium and pre-equilibrium reaction mechanisms, the (p,xn) cross-sections of the spallation neutron target nuclei Cr-50,Cr-52,Cr-53,Cr-54 and Cu-63,Cu-65 were investigated for incident proton ...
Molecular dynamics simulation of melting behaviour of small gold clusters: Au-N (N=12-14)
(Iop Publishing Ltd, 2007)
We have investigated the melting behaviour of AuN (N = 12 - 14) clusters by means of molecular dynamics simulation on the basis of the Voter - Chen version of the embedded-atom method. The melting behaviour of the clusters ...
Studies of Al-Ti AHoys by SEM
(Amer Inst Physics, 2007)
Al-Ti (1, 2 wt. %) alloys were investigated by Scanning Electron Microscopy (SEM). SEM observations and energy-dispersive x-ray analyses (EDX) showed that the phase structure of Al-Ti (1 %) alloy at 165 mu m/s is composed ...
The effects of zinc nitrate, zinc acetate and zinc chloride precursors on investigation of structural and optical properties of ZnO thin films
(Elsevier Science Sa, 2008)
ZnO thin films were prepared using zinc chloride, zinc acetate and zinc nitrate precursors by spray pyrolysis technique oil glass substrates at 550 degrees C. Structural and optical properties of ZnO films were investigated ...
Effect of cooling conditions on the magnetic properties of bainite transformation in an Fe-2%Mn-0.5%Cr alloy
(Elsevier Science Bv, 2008)
The effect of cooling conditions on the magnetic properties of bainitic reaction in Fe-2%Mn-0.5%Cr alloy have been investigated using Mossbauer spectroscopy. Results showed that the bainite phase is magnetically ordered ...
