Experimental study of the titanium nickelide thermophysical properties complex

Abstract

Abstract The article presents new experimental data on the thermal diffusivity (a), thermal conductivity (λ), heat capacity (Cp ) and linear thermal expansion coefficient (α) of titanium nickelide (56.6 wt. % Ni, 43.4 wt. % Ti). The temperature interval from 293 to 872…962 K has been investigated by laser flash technique, method of differential scanning calorimetry and dilatometric method. The estimated errors of the received data were 2–4%, 3–5%, 2–3% and (1.5–2)×10−7 K−1 for a, λ, Cp and α, respectively. The approximation dependences and the reference table of investigated transport, caloric and thermal properties have been obtained.
