“…The values estimated by Turnbull have been used for many years as a standard of the solid-liquid interfacial energy. Moreover, Gündüz and Hunt 3) estimated the solid-liquid interfacial energy in the Al-Cu, Al-Si and Pb-Sn systems from the shape of grain boundary cusps of alloys obtained from annealing in a temperature gradient on the basis of GibbsThomson effect. Recently, Yasuda and coworkers 4) estimated the solid-liquid interfacial energy of the Sn-Bi alloy from the relation between tip radius and growth velocity of the dendrites for metallic alloys obtained from the in-situ observation of solidification process using synchrotron radiation X-ray.…”

Solid-liquid interfacial energies of chromium and nickel are estimated from a Gibbs-Thomson relation. Molecular dynamics simulation shows that there is a critical temperature dividing shrinking or growing of a freestanding spherical crystal in the undercooled melt and the critical temperature is negatively correlated with inverse of crystal radius, which is regarded as the Gibbs-Thomson effect. The solid-liquid interfacial energies are then estimated from the proportional coefficient, to be 0.304 Jm -2 for chromium and 0.256 Jm -2 for nickel, respectively.

Molecular dynamics simulations have been performed to give an estimate on the solid-liquid interfacial properties of bcc iron, namely the kinetic coefficients and solid-liquid interfacial energy. The kinetic coefficients for different orientations were estimated from the propagation velocity of planar solid-liquid interfaces. The anisotropy of kinetic coefficients, m, was confirmed to be m (100) Ͼm (110) , which is similar to the literatures using other interatomic potentials. Moreover, growing and shrinking behavior of the freestanding spherical crystal and semi-spherical crystal on the substrate in the undercooled liquid was examined. There is a critical temperature dividing shrink or growth of both the freestanding spherical crystal and semi-spherical crystal on the substrate. The solid-liquid interfacial energy was then estimated from Gibbs-Thomson relation in the critical temperature as a function of the inverse of crystal radius.

“…As diffusion in the liquid phase is isotropic, the growth directions of dendrites, as well as their growth kinetics, are dictated by the anisotropy of the solid-liquid (s-') interfacial energy c s' . This anisotropy, which is typically less than a few per cent in metals, has been measured by the observation of the equilibrium shape of quenched droplets [2][3][4] or of the menisci at triple lines between two grains and the liquid in a thermal gradient [5,6].…”

The influence of solid–liquid interfacial energy anisotropy on equilibrium shapes, nucleation, triple lines and growth morphologies

et al. 2010

View full text Add to dashboard Cite

Abstract-The anisotropy of the solid-liquid interfacial energy plays a key role during the formation of as-solidified microstructures. Using the n-vector formalism of Cahn and Hoffman, this contribution presents the effect that anisotropy has on the equilibrium shapes of crystals and on surface tension equilibrium at triple lines. Consequences for heterogeneous nucleation of anisotropic crystals and for dendritic growth morphologies are detailed with specific examples related to Al-Zn and Zn-Al alloys.
