Interfacial Energies of Some Elemental and Alloy Aerospace Materials.

Abstract

Previously unreported values of the grain boundary free energies for pure titanium and the titanium alloy Ti-6Al-4V and of the surface free energy for the titanium alloy, as well as a new value of the surface free energy for pure titanium, have been determined using the zero-creep technique for small diameter wires and measurements of the dihedral angle at the base of thermally-etched grain boundary grooves. The temperature coefficients of the surface free energies and of the grain boundary free energies, as well as the self-diffusion coefficients, for pure titanium and for the Ti-6Al-4V alloy are reported.
