The equilibrated grain boundary groove shapes for the Cd solid solution in equilibrium with the Cd - Zn liquid have been observed by rapid quenching. From the observed grain boundary groove shapes, the Gibbs - Thomson coefficient and the solid - liquid surface energy for the Cd solid solution in equilibrium with the Cd - Zn eutectic liquid have been determined to be (8.16 +/- 0.65) x 10(-8) K m and (121 +/- 16) mJ m(-2) with the numerical method and from the Gibbs - Thomson equation, respectively. The grain boundary energy for the same material has been calculated as (241 +/- 30) mJ m(-2) from the observed grain boundary groove shapes. The thermal conductivities of the solid and liquid phases for Cd-26.5% Zn and Cd-5% Zn alloys have also been measured.
