Temperature dependences of density and ultrasound velocity of the eutectic Bi-44.6 wt.% Pb melt

Abstract

Measurements of temperature dependences of density d and ultrasound velocity V-s of the eutectic Bi-44.6 wt.% Pb alloy were performed from eutectic temperature up to 550-900 degrees C. Density was studied using gamma absorption method. Ultrasound velocity was determined by pulse phase method. The dependences V-s(T) and d(T) are linear in temperature interval of measurements and can be approximated by the equations: V-s(T) = 1788 - 0.269 (T - 398) m center dot s(-1). d(T) = 10271 - 1.29 (T - 398) kg center dot m(-3) These results are found to be in good agreement with data of other works.
