Abstract
The thermal conductivities of seven titanium alloys (VT1-0, VT18U, VT20, IMI834, Ti6242S, Ti6Al4V, and Ti6Al7Nb) have been measured. According to the data obtained, the room-temperature thermal conductivity of the investigated alloys varies from 6.4 to 7 W/(m K). A comparative analysis of the influence of alloying elements on the electronic structure and lattice parameters of the alloys has been performed. It is established that the thermal conductivity of titanium alloys increases with an increase in the atomic radius difference ∆
r
of the alloy (unit-cell volume) and with an increase in the average electron-to-atom ratio (
e
/
a
).
