Microscopic structure of liquid lead–potassium alloys: Neutron-diffraction and molecular-dynamics investigation
Static structure factors, S( Q), for liquid Pb–K alloys obtained by neutron diffraction and molecular-dynamics simulation are presented. Pure lead and the binary Pb–K system for potassium concentrations of 5, 14, 22, and 25 at% are investigated at 660 K. A satisfactory agreement of the experimental...

Summary: | Static structure factors,
S(
Q), for liquid Pb–K alloys obtained by neutron diffraction and molecular-dynamics simulation are presented. Pure lead and the binary Pb–K system for potassium concentrations of 5, 14, 22, and 25
at% are investigated at 660
K. A satisfactory agreement of the experimental data and simulated results is obtained. It is found that the characteristic prepeak of
S(
Q) at
Q∼1
Å
−1 disappears for alloys with potassium concentration less than ∼10
at%. Possible cluster configurations in the Pb–K alloys are revealed. |
