Abstract

The static structure factors S(Q) for liquid lead and Pb-K alloys obtained by neutron diffraction are presented. The binary system was investigated for potassium concentrations of 5, 14, 22, and 25 at. % at 660 K and for the eutectic point of 9 at. % at 630 K. A weak elevation of S(Q) is found in front of the main peak for the Pb0.95K0.05 and Pb0.91K0.09 alloys and a prepeak for the Pb0.86K0.14, Pb0.78K0.22, and Pb0.75K0.25 ones. This points to the formation of clusters for rising potassium concentration in liquid lead.
