Effect of boron on the thermal conductivity and thermal expansion of titanium

Conclusions Additions of boron substantially increase the thermal conductivity of titanium. A linear relationship is observed between the thermal conductivity of titanium-boron alloys and their boron content. It must be emphasized, however, that the rise in the thermal conductivity of these alloys cannot be ascribed solely to the formation of TiB₂ phase. The coefficient of linear expansion of titanium linearly decreases with rise in boron content up to a temperature of 500°C. Above this temperature, a more complex relationship is observed.Translated from Poroshkovaya Metallurgiya, No. 8 (92), pp. 78–82, August, 1970.
