Article Citation - WoS: 5Citation - Scopus: 5Solid-Liquid Interfacial Energy of Solid Succinonitrile in Equilibrium With Succinonitrile-1,4 Eutectic Liquid(Springer, 2015-01-28) Ersoy, S. B.; Altintas, Y.; Karadag, S. B.; Aksoz, S.; Keslioglu, K.; Marasli, N.; Karadağ, S.B.; Keşlioğlu, K.The grain boundary groove shapes for equilibrated solid SCN in equilibrium with the SCN-0.5 mol% DIB eutectic liquid have been directly observed by using a horizontal linear temperature gradient apparatus. The ratio of thermal conductivity of equilibrated liquid to thermal conductivity of solid SCN has also been determined to be 0.90. From the observed grain boundary groove shapes and measured thermal conductivity ratio, the Gibbs-Thomson coefficient (D") of solid SCN has been determined to be (5.46 +/- A 0.55) x 10(-8) K m. The solid-liquid interfacial energy (sigma (SL)) and the grain boundary energy of solid SCN have also been determined to be (8.25 +/- A 1.24) x 10(-3) J m(-2) and (15.84 +/- A 2.53) x 10(-3) J m(-2), respectively.Article Citation - WoS: 5Citation - Scopus: 6Experimental Determination of Interfacial Energies for Solid Sn in Equilibrium With Sn-Mg Liquid(Korean inst Metals Materials, 2015-03) Altintas, Yemliha; Ozturk, Esra; Aksoz, Sezen; Keslioglu, Kazim; Marasli, NecmettinThe equilibrated grain boundary groove shapes of solid Sn in equilibrium with Sn-Mg-Zn liquid were observed from a quenched sample by using a radial heat flow apparatus. The Gibbs-Thomson coefficient, solid-liquid interfacial energy and grain boundary energy of solid Sn were determined from the observed grain boundary groove shapes. The thermal conductivity of the eutectic solid phase for Sn-8.12 at% Mg-4.97 at% Zn alloy and the thermal conductivity ratio of the liquid phase to the solid phase for Sn-8.12 at% Mg-4.97 at% Zn alloy at eutectic temperature were also measured with a radial heat flow apparatus and a Bridgman-type growth apparatus, respectively. The Gibbs-Thomson coefficient, solid-liquid interfacial energy and grain boundary energy of solid Sn in equilibrium with Sn-Mg-Zn liquid were determined to be (8.3 +/- 0.6)x10(-8) Km, (118.5 +/- 14.2)x10(-3) Jm(-2) and (225.1 +/- 29.3)x10(-3) J m(-2) respectively from observed grain boundary groove shapes. A comparison of present results for solid Sn in the Sn-8.12 at% Mg-4.97 at% Zn alloy with the results obtained in previous works for similar solid Sn in equilibrium with different binary or ternary liquid was made.Article Citation - WoS: 6Citation - Scopus: 6Experimental Measurements of Some Thermophysical Properties of Solid CdSb Intermetallic in the Sn-Cd Ternary Alloy(Springer, 2016) Ozturk, Esra; Aksoz, Sezen; Altintas, Yemliha; Keslioglu, Kazum; Marasli, NecmettinThe equilibrated grain boundary groove shapes of solid CdSb in equilibrium with Sn-Cd-Sb eutectic liquid were observed from a quenched sample by using a radial heat flow apparatus. The Gibbs-Thomson coefficient, solid-liquid interfacial energy and grain boundary energy of the solid CdSb intermetallic were determined from the observed grain boundary groove shapes. The thermal conductivity of the eutectic solid and the thermal conductivity ratio of eutectic liquid to the eutectic solid in the Sn-35.8 at.%Cd-6.71 at.%Sb eutectic alloy at its eutectic melting temperature were also measured with a radial heat flow apparatus and a Bridgman-type growth apparatus, respectively.
