Solid–liquid interface energies in the succinonitrile and succinonitrile–carbon tetrabromide eutectic system

Calculation of the crystal-melt interfacial free energy of succinonitrile from molecular simulation

“…The magnitude of ␥ is found to be about 20% lower than the experimental value obtained by Schaefer et al, 29 but within the error bars of the more recent experimental result of Maraşli et al 30 The interfacial free energy is found to be very nearly isotropic, in agreement with experiment. 9,10 In addition, the Turnbull coefficient for succinonitrile from our simulation ͑0.35± 0.02͒ is in agreement with the experiments within the error bars.…”

“…͓͑8.9± 0.5͒ ϫ 10 −3 J m −2 ͔, but within the error bars of the more recent value of ͓͑7.9± 0.8͒ ϫ 10 −3 J m −2 ͔ of Maraşli et al 30 However, even given the large experimental uncertainty, it is reasonable to conclude that our value is at least 10% lower than the true experimental value. Our simulation indicates that the anisotropy in the interfacial free energy is very small.…”

“…39 Using these values, C T for SCN is found to be 0.33± 0.03 from the results of Maraşli et al 30 and 0.38± 0.02 from the results of Schaefer et al 29 The six-site model for succinonitrile gives 1.0108± 0.0008 g cm −3 for the equilibrium crystal density and a latent heat of 3.11± 0.19 kJ mol −1 , which results in a C T of 0.35± 0.02. So the value of the Turnbull coefficient from the simulation is in agreement ͑within the error bars͒ with both experimental measurements, as well as being close to Turnbull's predictions for semimetals and water ͑0.32͒.…”

Experimental determination of solid-liquid interfacial energy for Zn solid solution in equilibrium with the Zn-Al eutectic liquid

“…They measured solid-solid and solid-liquid interface energies in the Al-CuAl 2 and Al-NiAl 3 eutectic systems and Al-Ti peritectic system. More recently, Bayender et al, [15,16] Maraşli et al, [17] Keşlioglu and Maraşli, [18] and Erol et al [19] have observed the equilibrated grain boundary groove shapes for transparent and opaque materials. They applied Gündüz and Hunt's numerical method to determine Gibbs-Thomson coefficients, solid-liquid interface energies, and grain boundary energies in camphene, pivalic acid, succinonitrile and succinonitrile-carbontetra bromide, Al-Zn, and Bi-Cd binary eutectic systems.…”

Measurement of Solid-Liquid Interfacial Energy for Solid Zn in Equilibrium with the ZnMg Eutectic Liquid

“…[13][14][15][16][17][18][19][20][21] The aim of the present work was to determine the GibbsThomson coefficient, solid-liquid interfacial energy, and grain boundary energy from observed grain boundary groove shapes. A radial heat flow apparatus originally designed by Gündüz and Hunt [10,11] was used to observe the equilibrated grain boundary groove shapes for Zn solid in equilibrium with the ZnMg eutectic liquid.…”
