Thermal grooving by surface diffusion: a review of classical thermo-kinetics approach
(Hitit University, 2017)
In polycrystalline materials wherever a grain boundary intersects a free surface and whenever the topographic variation associated with the atomic motion is favored by total free energy dissipation, the material surface ...
Simulation of phase equilibria in high chromium white cast irons
(Uludağ University, 2018-12)
In this study, using the Materials Calculator software program, the pseudo binary phase diagrams (i.e. isoplethal maps) of high chromium white cast irons (~19% in weight) with different molybdenum contents were simulated. ...
Synthesis, characterization and electrochemical performance of Nb doped LiFePO4/C cathodes by mechanochemical activation
(Hitit University, 2018)
We synthesized Nb-doped LiFePO4/C nano composite cathode materials by mechanochemical activation followed by a single step calcination. The starting chemicals of Li2CO3, FeC2O4.2H2O, NH4H2.PO4 and C6H8O7 as lithium, iron, ...
The thermodynamic stability of intermediate solid solutions in LiFePO4 nanoparticles
(Royal Society of Chemistry, 2016)
Theoretical predictions from first principles and recent advances in in situ electrochemical characterization techniques have confirmed the presence of solid-solution states during electrochemical (de)lithiation of LiFePO4 ...
Particle-size and morphology dependence of the preferred interface orientation in LiFePO4 nano-particles
(Royal Society of Chemistry, 2014)
We gain new insights into the equilibrium properties and potential two-phase lithiation mechanisms in LiFePO4 nano-particles by conducting a first-principles investigation of the anisotropic chemical interfacial energy ...
Predicting microstructure evolution during directed energy deposition additive manufacturing of Ti-6Al-4V
(American Society of Mechanical Engineers (ASME), 2018)
Laser engineering net shaping (LENS) is one of the representative processes of directed energy deposition (DED) in which a moving heat source having high-intensity melts and fuses metal powders together to print parts. The ...
