The thermal and mechanical properties of Cu, Au pure metals and their ordered intermetallic alloys of Cu3Au(L1(2)), CuAu(L1(0)) and CuAu3(L1(2)) are studied by using the molecular dynamics simulation. The effects of temperature and concentration on the physical properties of CuxAu1-x, are analysed. Sutton-Chen (SC) and quantum Sutton-Chen (Q-SC) many-body potentials are used. The simulation results such as cohesive energy, density, elastic constants, bulk modulus, heat capacity, thermal expansion, melting points and phonon dispersion curves are in good agreement with the available experimental data at the various temperatures. Q-SC potential parameter results are usually closer to experimental values than the ones predicted from SC potential parameters.

Modelling and Monte Carlo simulation of the atomic ordering processes in Ni3Al intermetallics Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (IOP Publishing, 2007-03-01) The evolution of atomic ordering processes in Ni3Al has been modelled by a Monte Carlo ( MC) simulation method combined with the electronic theory of alloys in pseudopotential approximation. The magnitudes of atomic ordering energies of atomic pairs in the Ni3Al system have been calculated by means of electronic theory in pseudopotential approximation up to the 4th coordination spheres and subsequently used as input data for MC simulation for more detailed analysis for the first time. The Bragg - Williams l...
Temperature dependence of magnetic and thermal properties of chiral HyFe and HyMn close to phase transitions by using the Landau mean field model Tari, Ozlem; Yurtseven, Hasan Hamit (Elsevier BV, 2019-04-15) Magnetic and thermal properties of chiral metal formate frameworks (MOFs) of NH2NH3M(HCOO)(3), M = Fe, Mn, namely, HyFe and HyMn are investigated close to phase transitions by using Landau phenomenological model. By expanding the free energy in terms of the order parameter, for magnetic properties the temperature dependence of magnetization and inverse magnetic susceptibility, and for thermal properties the heat capacity and entropy are calculated for chiral HyFe and HyMn close to phase transitions using th...
BCC single crystal plasticity modeling and its experimental identification Yalçınkaya, Tuncay; Geers, M.G.D. (IOP Publishing, 2008-12-01) A crystal plasticity model for body-centered-cubic (BCC) single crystals, taking into account the plastic anisotropy due to non-planar spreading of screw dislocation cores is presented. In view of the longstanding contradictory statements on the deformation of BCC single crystals and their macroscopic slip planes, recent insights and developments are reported and included in this model. The flow stress of BCC single crystals shows a pronounced dependence on the crystal orientation and the temperature, mostl...
Mechanical and microstructural evaluations of hot formed titanium sheets by electrical resistance heating process Ozturk, Fahrettin; Ece, Remzi Ecmel; Polat, Naki; Koksal, Arif; Evis, Zafer; Polat, Aytekin (Elsevier BV, 2013-08-20) In this study, effect of temperature in the electrical resistance heating process on mechanical properties and microstructures of commercially pure titanium grade 2 (CP2) and Ti-6Al-4V (T64) alloy sheets was investigated. Sheets were successfully heated by the electric resistance heating process, and their mechanical properties and microstructures were evaluated. Ductilities of both materials were increased significantly after 400 degrees C. Results indicate that no significant change was observed in grain ...
Structural, thermodynamical, and transport properties of undercooled binary Pd-Ni alloys Kart, S. Ozdemir; Tomak, Mehmet; Uludogan, M.; Cagin, T. (Elsevier BV, 2006-11-05) The solidification properties of Pd-Ni alloys are studied with constant-pressure, constant-temperature (TPN), and constant-volume, constant-temperature (TVN) molecular dynamics simulations based on quantum Sutton-Chen potential. Whether the system forms the glass structure or it transforms into ordered state is checked at various cooling rates ranging from 10 K/ps to 0.05 K/ps. The effect of concentration and cooling rates on the glass transition temperature is examined. The behavior of heat capacity at con...
