Thermal and electrical properties of porous titanium

Conclusions The thermal conductivity, coefficients of thermal expansion and thermo-emf, and electrical resistivity of porous titanium have been determined in the temperature range from ambient to 800–1200°C. The effect of specimen porosity on the character of the thermal and electrical conductivities of porous titanium has been established. A study has been made of the effect of the- phase transformation on the electrical conductivity and thermo-emf of porous titanium. The thermal conductivity may be evaluated from the electrical conductivity with the aid of an experimentally established value of Lorentz number.Translated from Poroshkovaya Metallurgiya, No. 8 (92), pp. 35–38, August, 1970.
