The Thermal Conductivity of Ti-5Al-2.5 Sn between 1.2 and 35 K: The Effect of Plastic Deformation
Measurements of the thermal conductivity of swaged and annealed samples of Ti-5A1-2.5 Sn have been made between 1.2 and 35 K. The thermal conductivity of the annealed material increases uniformly from a value of 1.67 × 10−3 w cm−1 K−1 at 2 K to 28.3 × 10−3 w cm−1 K−1 at 30 K. The thermal conductivities of the swaged specimens are roughly 65% of those of the annealed throughout this temperature range. The measured thermal conductivities. The difference between the lattice thermal conductivities of the swaged and annealed samples cannot be explained in terms of phonon scattering by a random arrangement of sessile dislocations.
