Abstract

Heat of formation measurements and calculations of free energies of formation at 80 to 273 K lead to the following conclusions. The liquisol- quenched phases X (56 at. % Bi) and Y (89 at. % Bi) are unstable at 80 to 273 K. The high temperature equilibrium phase epsilon is also unstable at 80 K. The apparent stabilities of the lead bismuth intermediate phases at low temperatures may be attributed to kinetic inhibitions to decomposition in the solid state. A metastable constitution diagram at 80 K is plotted.
