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

Measurements of temperature dependences of density d and ultrasound velocity Vs of the eutectic Bi-44.6 wt.% Pb alloy were performed from eutectic temperature up to 550–900◦C. Density was studied using gamma absorption method. Ultrasound velocity was determined by pulse phase method. The dependences Vs(T ) and d(T ) are linear in temperature interval of measurements and can be approximated by the equations: Vs(T ) = 1788 − 0.269 (T − 398) m· s−1. d(T ) = 10271 − 1.29 (T − 398) kg ·m−3. These results are found to be in good agreement with data of other works. C 2005 Springer Science + Business Media, Inc.
