Solid-liquid surface energies in the Al-CuAl2, Al-NiAl3 and Al-Ti systems

The Gibbs-Thomson coefficients and the solid-liquid surface energies in the Al-CuAl2, Al-NiAl3 eutectic systems and Al-Ti peritectic system have been measured by a direct method. The solid Al-solid CuAl2 surface energy and the grain boundary energies in the Al-NiAl3 eutectic and A1-Ti peritectic systems have been calculated from the measured grain boundary cusps. The thermal conductivity of both solid and liquid phases for the Al-6.4 wt% Ni and Al-0.22 wt% Ti alloys were also measured.
