Experimental study of the titanium nickelide thermophysical properties complex

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.
