Evaluation of Viscosity of Bi–Pb Melt (56.5%–43.5%) by the Width of a Weak Shock Wave

Abstract

Experimental evaluation of the viscosity of 56.5% Bi–43.5% Pb eutectic melt at 150°С in a pressure range from 3 to 32 GPa on the basis of measurement of the shock wave width has been carried out. It was found that melt viscosity increases by 3–4 orders of magnitude under compression as compared to standard measurements at atmospheric pressure.
