Thermal conductivity at about 85 K, κ, and resistivity at liquid nitrogen temperature (LN), ρLN, of a Ti–15 mass%V–3 mass%Cr–3 mass%Sn–3 mass%Al (Ti–15–3) alloy in variously aged states were measured by steady state method and direct current 4-contacts method, respectively. Thermal conductivity at room temperature (RT) and about 85 K of the Ti–15–3 alloy specimens quenched from 1073 K was smaller than that of other titanium alloys and SUS304 stainless steel. Thermal conductivity at about 85 K was increased by accumulative isochronal aging (step heating) up to 823 K and by isothermal aging at 773 K, while resistivity at LN decreased with the aging. The increase and the decrease were ascribed to α precipitation. All values of thermal conductivity measured in the aged Ti–15–3 alloy were about a half of that of SUS304 stainless steel. Relationship between thermal conductivity at about 85 K and the average measuring temperature in steady state divided by the resistivity at LN was almost linear, and regressed equation was κ = 0.11(ρLN−1T) −1.60, where the units are W·m−1·K−1 for κ, μΩ·m for ρLN and K for T.
